AToM Static Pseudowire Provisioning

The AToM Static Pseudowire Provisioning feature allows provisioning an Any Transport over Multiprotocol Label Switching (MPLS) (AToM) static pseudowire without the use of a directed control connection. In environments that do not or cannot use directed control protocols, this feature provides a means for provisioning the pseudowire parameters statically at the Cisco IOS command-line interface (CLI).

Restrictions for AToM Static Pseudowire Provisioning

The following parameters are exchanged using directed control protocol messages on pseudowires, but cannot be changed using the AToM Static Pseudowire Provisioning feature introduced in Cisco IOS Release 12.33(SRB). Instead, the software has preconfigured defaults.

  • The Virtual Circuit Connectivity Verification (VCCV) options used for fault detection, isolation, and verification at both ends of the connection are set as follows:
    • Control channel type 1 sets the control word.
    • Control channel type 2 sets the MPLS router alert label.
    • Connectivity verification type 2 sets the label switched path (LSP) ping command.

In Cisco IOS Release 12.2(33)SRE, support for cell packing for static pseudowires was added. This feature has the following restrictions:

  • Both provider-edge routers (PEs) must run Cisco IOS Release 12.2(33)SRE, and the maximum number of cells that can be packed must be set to the same value on each PE router.
  • Autosensing of the virtual circuit type for Ethernet over MPLS is not supported.

Additionally, the following functionality is not supported for static pseudowires:

  • Sequence number resynchronization—configured by the sequencing function in the pseudowire-class command—is not supported because the sequence number resynchronization is done when the Label Distribution Protocol (LDP) software sends an LDP Label Release or Withdraw message followed by a Label Request or Mapping message, and static pseudowires do not use LDP.
  • Tunnel stitching is not supported because it requires an extension of the neighbor command to start the mode that allows configuring static pseudowire parameters such as remote and local labels. Note that a tunnel switch point can be configured using a different static label command. The tunnel switch point will not process control words, but label swapping will occur.
  • Pseudowire redundancy is not supported because it requires using a directed control protocol between the peer provider edge routers.

Information About AToM Static Pseudowire Provisioning

Pseudowire Provisioning

The AToM Static Pseudowire Provisioning feature allows you to configure static pseudowires in cases where you cannot use directed control protocols. .In most cases, pseudowires are dynamically provisioned using LDP or another directed control protocol, such as Resource Reservation Protocol over traffic-engineered tunnels (RSVP-TE), to exchange the various parameters required for these connections.

The AToM Static Pseudowire Provisioning feature is platform-independent, but has been tested on only the Cisco 7600 series routers.

Benefits of Statically Provisioned Pseudowires

This feature allows provisioning an AToM label switching static pseudowire without the use of a directed control connection. This feature also includes static provisioning of the tunnel label and the pseudowire label.

How to Provision an AToM Static Pseudowire

Provisioning an AToM Static Pseudowire

In this configuration task, you use options in the xconnect Ethernet interface configuration command to specify a static connection, and mpls commands in xconnect mode to statically set the following pseudowire parameters:

  • Set the local and remote pseudowire labels
  • Enable or disable sending the MPLS control word
SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    interface ethernet-type interface-number

    4.    xconnect peer-ip-address vcid encapsulation mpls manual pw-class class-name

    5.    mpls label local-pseudowire-label remote-pseudowire-label

    6.    [no] mpls control-word

    7.    exit


DETAILED STEPS
     Command or ActionPurpose
    Step 1 enable


    Example:
    Router> enable
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.
     
    Step 2 configure terminal


    Example:
    Router# configure terminal
     

    Enters global configuration mode.

     
    Step 3 interface ethernet-type interface-number


    Example:
    Router(config)# interface Ethernet 1/0
     

    Enters interface configuration mode for the specified interface.

     
    Step 4 xconnect peer-ip-address vcid encapsulation mpls manual pw-class class-name


    Example:
    Router(config-if)# xconnect 10.131.191.252 100 encapsulation mpls manual pw-class mpls
     

    Configures a static AToM pseudowire and enters xconnect configuration mode where the local and remote pseudowire labels are set.

     
    Step 5 mpls label local-pseudowire-label remote-pseudowire-label


    Example:
    Router(config-if-xconn)# mpls label 100 150
     

    Sets the local and remote pseudowire labels.

    • The label must be an unused static label within the static label range configured using the mpls label range command.
    • The mpls label command checks the validity of the label entered and displays an error message if it is not valid. The label supplied for the remote-pseudowire-labelargument must be the value of the peer PE’s local pseudowire label.
     
    Step 6 [no] mpls control-word

    Example:
    Router(config-if-xconn)# no mpls control-word
     

    Sets whether the MPLS control word is sent.

    • This command must be set for Frame Relay data-link connection identifier (DLCI) and ATM adaptation layer 5 (AAL5) attachment circuits. For other attachment circuits, the control word is included by default.
    • If you enable inclusion of the control word, it must be enabled on both ends of the connection for the circuit to work properly.
    • Inclusion of the control word can be explicitly disabled using the no mpls control-word command.
     
    Step 7 exit


    Example:
    Router(config-if-xconn)# exit
     

    Exits the configuration mode.

    • Continue entering the exitcommand at the router prompt until you reach the desired configuration mode.
     

    Verifying the AToM Static Pseudowire Configuration

    To verify the AToM static pseudowire configuration, use the show running-config EXEC command. To verify that the AToM static pseudowire was provisioned correctly, use the show mpls l2transport vc detailand ping mpls pseudowireEXEC commands as described in the following steps.

    SUMMARY STEPS

      1.    show mpls l2transport vc detail

      2.    ping mpls pseudowire ipv4-address vc-id vc-id


    DETAILED STEPS
      Step 1   show mpls l2transport vc detail

      For nonstatic pseudowire configurations, this command lists the type of protocol used to send the MPLS labels (such as LDP). For static pseudowire configuration, the value of the signaling protocol field should be Manual. Following is sample output:



      Example:
      Router# show mpls l2transport vc detail
      Local interface: Et1/0 up, line protocol up, Ethernet up
        Destination address: 10.0.1.1, VC ID: 200, VC status: up
          Output interface: Et3/0, imposed label stack {17}
          Preferred path: not configured  
          Default path:
          Next hop: 10.0.0.2
        Create time: 00:27:27, last status change time: 00:27:24
        Signaling protocol: Manual
          MPLS VC labels: local 17, remote 17 
          Group ID: local 0, remote 0
          MTU: local 1500, remote 1500
        Sequencing: receive disabled, send disabled
        VC statistics:
          packet totals: receive 193, send 193
          byte totals:   receive 19728, send 23554
          packet drops:  receive 0, send 0
      
      Step 2   ping mpls pseudowire ipv4-address vc-id vc-id

      Because there is no directed control protocol exchange of parameters on a static pseudowire, both ends of the connection must be correctly configured. One way to detect mismatch of labels or control word options is to send an MPLS pseudowire LSP ping command as part of configuration task, and then reconfigure the connection if problems are detected. An exclamation point (!) is displayed when the ping command is successfully sent to its destination. An example of command use and output follows:



      Example:
      Router# ping mpls pseudowire 10.7.1.2 vc-id 1001
      Sending 5, 100-byte MPLS Echos to 10.7.1.2,
            timeout is 2 seconds, send interval is 0 msec:
      Codes: '!' - success, 'Q' - request not sent, '.' - timeout,
         'L' - labeled output interface, 'B' - unlabeled output interface,
         'D' - DS Map mismatch, 'F' - no FEC mapping, 'f' - FEC mismatch,
         'M' - malformed request, 'm' - unsupported tlvs, 'N' - no label entry,
         'P' - no rx intf label prot, 'p' - premature termination of LSP,
         'R' - transit router, 'I' - unknown upstream index,
         'X' - unknown return code, 'x' - return code 0
      Type escape sequence to abort.
      !!!!!
      Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

      Configuration Examples for AToM Static Pseudowire Provisioning

      Provisioning an AToM Pseudowire Example

      The following examples show the configuration commands for an AToM static pseudowire connection between two PEs, PE1 and PE2.

      The mpls label range static command must be used to configure the static label range prior to provisioning the AToM static pseudowire.

      Router# configure terminal
      Router(config)# mpls label range 200 16000 static 16 199
      % Label range changes will take effect at the next reload.

      The mpls ip command must also be configured on the core-facing interface of both PE1 and PE2 (which is also done for directed control protocol signaled pseudowires). Following is a configuration example:

      Router(config)# interface Ethernet 0/0
      Router(config-if)# description Backbone interface
      Router(config-if)# ip address 10.0.0.1 255.255.255.0
      Router(config-if)# mpls ip
      Router(config-if)# exit
      

      Following is an example AToM static pseudowire configuration for PE1:

      Router(config)# interface Ethernet 1/0
      Router(config-if)# no ip address
      Router(config-if)# xconnect 10.131.191.251 100 encapsulation mpls manual pw-class mpls
      Router(config-if-xconn)# mpls label 100 150
      Router(config-if-xconn)# exit
      

      Following is an example AToM static pseudowire configuration for PE2:

      Router(config)# interface Ethernet 1/0
      Router(config-if)# no ip address
      Router(config-if)# xconnect 10.132.192.252 100 encapsulation mpls manual pw-class mpls
      Router(config-if-xconn)# mpls label 150 100
      Router(config-if-xconn)# exit
      

      This feature also allows tunnel labels to be statically configured using the mpls static binding ipv4 vrf command. See the MPLS Static Labels feature module and the Cisco IOS Multiprotocol Label Switching Command Reference for information about static labels and the mpls static binding ipv4 vrfcommand.

      Benefits of Statically Provisioned Pseudowires

      This feature allows provisioning an AToM label switching static pseudowire without the use of a directed control connection. This feature also includes static provisioning of the tunnel label and the pseudowire label.

      How to Provision an AToM Static Pseudowire

      Provisioning an AToM Static Pseudowire

      In this configuration task, you use options in the xconnect Ethernet interface configuration command to specify a static connection, and mpls commands in xconnect mode to statically set the following pseudowire parameters:

      • Set the local and remote pseudowire labels
      • Enable or disable sending the MPLS control word
      SUMMARY STEPS

        1.    enable

        2.    configure terminal

        3.    interface ethernet-type interface-number

        4.    xconnect peer-ip-address vcid encapsulation mpls manual pw-class class-name

        5.    mpls label local-pseudowire-label remote-pseudowire-label

        6.    [no] mpls control-word

        7.    exit


      DETAILED STEPS
         Command or ActionPurpose
        Step 1 enable


        Example:
        Router> enable
         

        Enables privileged EXEC mode.

        • Enter your password if prompted.
         
        Step 2 configure terminal


        Example:
        Router# configure terminal
         

        Enters global configuration mode.

         
        Step 3 interface ethernet-type interface-number


        Example:
        Router(config)# interface Ethernet 1/0
         

        Enters interface configuration mode for the specified interface.

         
        Step 4 xconnect peer-ip-address vcid encapsulation mpls manual pw-class class-name


        Example:
        Router(config-if)# xconnect 10.131.191.252 100 encapsulation mpls manual pw-class mpls
         

        Configures a static AToM pseudowire and enters xconnect configuration mode where the local and remote pseudowire labels are set.

         
        Step 5 mpls label local-pseudowire-label remote-pseudowire-label


        Example:
        Router(config-if-xconn)# mpls label 100 150
         

        Sets the local and remote pseudowire labels.

        • The label must be an unused static label within the static label range configured using the mpls label range command.
        • The mpls label command checks the validity of the label entered and displays an error message if it is not valid. The label supplied for the remote-pseudowire-labelargument must be the value of the peer PE’s local pseudowire label.
         
        Step 6 [no] mpls control-word

        Example:
        Router(config-if-xconn)# no mpls control-word
         

        Sets whether the MPLS control word is sent.

        • This command must be set for Frame Relay data-link connection identifier (DLCI) and ATM adaptation layer 5 (AAL5) attachment circuits. For other attachment circuits, the control word is included by default.
        • If you enable inclusion of the control word, it must be enabled on both ends of the connection for the circuit to work properly.
        • Inclusion of the control word can be explicitly disabled using the no mpls control-word command.
         
        Step 7 exit


        Example:
        Router(config-if-xconn)# exit
         

        Exits the configuration mode.

        • Continue entering the exitcommand at the router prompt until you reach the desired configuration mode.
         

        Verifying the AToM Static Pseudowire Configuration

        To verify the AToM static pseudowire configuration, use the show running-config EXEC command. To verify that the AToM static pseudowire was provisioned correctly, use the show mpls l2transport vc detailand ping mpls pseudowireEXEC commands as described in the following steps.

        SUMMARY STEPS

          1.    show mpls l2transport vc detail

          2.    ping mpls pseudowire ipv4-address vc-id vc-id


        DETAILED STEPS
          Step 1   show mpls l2transport vc detail

          For nonstatic pseudowire configurations, this command lists the type of protocol used to send the MPLS labels (such as LDP). For static pseudowire configuration, the value of the signaling protocol field should be Manual. Following is sample output:



          Example:
          Router# show mpls l2transport vc detail
          Local interface: Et1/0 up, line protocol up, Ethernet up
            Destination address: 10.0.1.1, VC ID: 200, VC status: up
              Output interface: Et3/0, imposed label stack {17}
              Preferred path: not configured  
              Default path:
              Next hop: 10.0.0.2
            Create time: 00:27:27, last status change time: 00:27:24
            Signaling protocol: Manual
              MPLS VC labels: local 17, remote 17 
              Group ID: local 0, remote 0
              MTU: local 1500, remote 1500
            Sequencing: receive disabled, send disabled
            VC statistics:
              packet totals: receive 193, send 193
              byte totals:   receive 19728, send 23554
              packet drops:  receive 0, send 0
          
          Step 2   ping mpls pseudowire ipv4-address vc-id vc-id

          Because there is no directed control protocol exchange of parameters on a static pseudowire, both ends of the connection must be correctly configured. One way to detect mismatch of labels or control word options is to send an MPLS pseudowire LSP ping command as part of configuration task, and then reconfigure the connection if problems are detected. An exclamation point (!) is displayed when the ping command is successfully sent to its destination. An example of command use and output follows:



          Example:
          Router# ping mpls pseudowire 10.7.1.2 vc-id 1001
          Sending 5, 100-byte MPLS Echos to 10.7.1.2,
                timeout is 2 seconds, send interval is 0 msec:
          Codes: '!' - success, 'Q' - request not sent, '.' - timeout,
             'L' - labeled output interface, 'B' - unlabeled output interface,
             'D' - DS Map mismatch, 'F' - no FEC mapping, 'f' - FEC mismatch,
             'M' - malformed request, 'm' - unsupported tlvs, 'N' - no label entry,
             'P' - no rx intf label prot, 'p' - premature termination of LSP,
             'R' - transit router, 'I' - unknown upstream index,
             'X' - unknown return code, 'x' - return code 0
          Type escape sequence to abort.
          !!!!!
          Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

          The mpls label range static command must be used to configure the static label range prior to provisioning the AToM static pseudowire.

          Router# configure terminal
          Router(config)# mpls label range 200 16000 static 16 199
          % Label range changes will take effect at the next reload.

          The mpls ip command must also be configured on the core-facing interface of both PE1 and PE2 (which is also done for directed control protocol signaled pseudowires). Following is a configuration example:

          Router(config)# interface Ethernet 0/0
          Router(config-if)# description Backbone interface
          Router(config-if)# ip address 10.0.0.1 255.255.255.0
          Router(config-if)# mpls ip
          Router(config-if)# exit
          

          Following is an example AToM static pseudowire configuration for PE1:

          Router(config)# interface Ethernet 1/0
          Router(config-if)# no ip address
          Router(config-if)# xconnect 10.131.191.251 100 encapsulation mpls manual pw-class mpls
          Router(config-if-xconn)# mpls label 100 150
          Router(config-if-xconn)# exit
          

          Following is an example AToM static pseudowire configuration for PE2:

          Router(config)# interface Ethernet 1/0
          Router(config-if)# no ip address
          Router(config-if)# xconnect 10.132.192.252 100 encapsulation mpls manual pw-class mpls
          Router(config-if-xconn)# mpls label 150 100
          Router(config-if-xconn)# exit
          

          This feature also allows tunnel labels to be statically configured using the mpls static binding ipv4 vrf command. See the MPLS Static Labels feature module and the Cisco IOS Multiprotocol Label Switching Command Reference for information about static labels and the mpls static binding ipv4 vrfcommand.
