This topic describes how to associate a Bridge-Group Virtual Interface (BVI) as the routed interface on a bridge domain by creating the bridge group and bridge domain and applying the routed interface BVI configuration.

To associate the BVI as the routed interface on a bridge domain, complete the following steps.

Procedure

  1. In the global configuration mode, run the l2vpn command to enter the L2VPN configuration mode.

    Example:

    
Router(config)#l2vpn

  2. Create a bridge group and enter the L2VPN bridge group configuration mode.

    Example:

    Router(config-l2vpn)#bridge group BG_test

  3. Run the bridge-domain bridge-domain-name command to create a bridge domain and enter the L2VPN bridge group bridge domain configuration mode.

    Example:

    Router(config-l2vpn-bg)#bridge-domain 1

  4. Associate the specified BVI as the routed interface for the interfaces that are assigned to the bridge domain.

    Example:

    Router(config-l2vpn-bg-bd)# routed interface bvi 1

  5. Run the end or commit commands to save the configuration.

    Example:

    
Router(config-l2vpn-bg-bd)#end

    or

    Router(config-l2vpn-bg-bd)#commit

    • When you issue the end command, the system prompts you to commit changes:

      
Uncommitted changes found, commit them before exiting(yes/no/cancel)?
[cancel]:

    • Entering yes saves configuration changes to the running configuration file, exits the configuration session, and returns the router to EXEC mode.

    • Entering no exits the configuration session and returns the router to EXEC mode without committing the configuration changes.

    • Entering cancel leaves the router in the current configuration session without exiting or committing the configuration changes.

    • Use the commit command to save the configuration changes to the running configuration file and remain within the configuration session.
