VRF-Aware SCP

The VRF-Aware SCP feature applies the secure copy protocol (SCP) functionality to Virtual Routing and Forwarding (VRF) interfaces using the Secure Shell (SSH) application to copy device configurations or device image files.

Prerequisites for VRF-Aware SCP

  • Ensure that Secure Shell (SSH) connection is enabled.

  • Ensure that Virtual Routing and Forwarding (VRF) configuration is available on the device.

Information About VRF-Aware SCP

SCP and SSH

The secure copy protocol (SCP) feature allows a user with appropriate authorization to copy any file that exists in the Cisco IOS File System (IFS) to and from a device by using the copy command. Being Virtual Routing and Forwarding (VRF) aware, the SCP feature can provide the service only to a specific group or interface rather than providing global access and configuration. The VRF-aware SCP feature enables administrators to have more control and added security.

SCP relies on Secure Shell (SSH) for security and authentication.

Use the ip ssh source-interface command to source SSH traffic from any interface, including a VRF interface.

How to Configure VRF-Aware SCP

Configuring SCP to Use VRF-Aware Interface

Before You Begin

Configure Virtual Routing and Forwarding (VRF) aware interfaces.

SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    ip ssh source-interface interface

    4.    exit

    5.    copy running-config scp://username@destination-host-address[/destination-directory][/destination-filename]

    6.    copy scp://username@source-host-address[/source-directory][/source-filename] bootflash:

    7.    exit


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 ip ssh source-interface interface


    Example: 
    Device(config)# ip ssh source-interface GigabitEthernet 1/1
     

    Specifies the IP address of an interface as the source address for a Secure Shell (SSH) client device. Provide a VRF-aware interface to use the VRF-Aware SCP feature.

     
    Step 4 exit


    Example: 
    Device(config)# exit
     

    Exits global configuration mode and returns to privileged EXEC mode.

     
    Step 5 copy running-config scp://username@destination-host-address[/destination-directory][/destination-filename]


    Example: 
    Device# copy running-config scp://guest@10.76.76.160/router.cfg
     

    Copies a file from the current running configuration file of the source device to a destination device with secure copy protocol (SCP).

     
    Step 6 copy scp://username@source-host-address[/source-directory][/source-filename] bootflash:


    Example: 
    Device# copy scp://guest@10.76.76.160/router.cfg bootflash:
     

    Copies a file to the boot flash memory of the destination device from the source device with SCP.

     
    Step 7 exit


    Example: 
    Device# exit
     

    Exits privileged EXEC mode and returns to user EXEC mode.
