Information About IPv6 Static Route Support for Object Tracking

IPv6 Static Route Support for Object Tracking

The ipv6 route command will allow an IPv6 static route to be associated with a tracked-object.

Routing Table Insertion

An IPv6 static route associated with a tracked-object is inserted into the IPv6 routing table if the state of the tracked-object is up and if all other routing-table-insertion criteria are met.

Routing Table Insertion Criteria

An IPv6 static route may be inserted into the IPv6 routing table if the following insertion criteria are met:

  1. Interface is up.
  2. Next-hop address is not the device's own address.
  3. Next-hop address is in scope.
  4. Next-hop address is resolved.
  5. Bidirectional Forwarding Detection (BFD) session is up, if the BFD tracking is configured.

    Note
    An IPv6 static route may be associated with both a tracked object and a BFD session. Both tracked object and BFD session state must be up before the IPv6 static route is inserted in the routing table.
  6. Tracked object state is up.

An IPv6 static route resident in the routing table is removed if any of the insertion criteria becomes false.

How to Configure IPv6 Static Route Support for Object Tracking

Configuring the IPv6 Static Routing Support for Object Tracking

SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    ipv6 route {vrf table-name-id ipv6-prefix interface interface number [admin-distance object-number | ipv6-adress object-number | multicast object-number | name object-number | nexthop-vrf object-number | tag object-number | track object-number | unicastobject-number ]}

    4.    end

    5.    show track object-number


DETAILED STEPS
     Command or ActionPurpose
    Step 1 enable


    Example: 
    Device> enable
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.
     
    Step 2 configure terminal


    Example: 
    Device# configure terminal
     

    Enters global configuration mode.

     
    Step 3 ipv6 route {vrf table-name-id ipv6-prefix interface interface number [admin-distance object-number | ipv6-adress object-number | multicast object-number | name object-number | nexthop-vrf object-number | tag object-number | track object-number | unicastobject-number ]}


    Example: 
    Device(config)# ipv6 route vrf 0x0 2001:DB8:1:2::/64 fastEthernet0/0 2001:DB8:3:4::1 track 42
     

    IPv6 static route object tracking is configured by adding the track object-number to the static route configuration.

     
    Step 4 end


    Example: 
    Device(config)# end
     

    Exits to privileged EXEC mode.

     
    Step 5show track object-number


    Example: 
    Device(config)# show track 42
     

    (Optional) Displays tracking information.

    • Use this command to verify the configuration.
    Note   

    The status of a static route associated with a tracked-object can be obtained by issuing the command show ipv6 static [vrf id] detail. This command shows whether the static route has been installed in the routing-table and the reasons if the static route has not been installed.
