Configure IS-IS Multi-area SPB IPv4 Unicast Redistribution

Before you begin

Configure IP Shortcuts on the boundary nodes.

About this task

Perform this procedure to configure Multi-area SPB IPv4 unicast redistribution on the switch.

Procedure

  1. Enter IS-IS Router Configuration mode:

    enable

    configure terminal

    router isis

  2. Create the Multi-area SPB IPv4 unicast redistribution instance:

    multi-area ip redistribute unicast [home-to-remote | remote-to-home]

    Note

    Note

    If you do not specify the direction for redistribution then the system applies the redistribution in both directions by default.

  3. Optional: Configure a route policy to govern the redistribution:

    multi-area ip redistribute unicast [home-to-remote | remote-to-home] route-map WORD<1-64>

  4. Enable the Multi-area SPB IPv4 unicast redistribution instance:

    multi-area ip redistribute unicast [home-to-remote | remote-to-home] enable

  5. Verify the Multi-area SPB IPv4 unicast redistribution configuration:

    show isis multi-area ip redistribute unicast [home-to-remote | remote-to-home]

  6. Apply the Multi-area SPB IPv4 unicast redistribution:

    isis multi-area ip apply redistribute unicast [home-to-remote | remote-to-home]

Example

Configuring Multi-area SPB IPv4 unicast redistribution for home to remote direction:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#router isis
Switch:1(config-isis)#multi-area ip redistribute unicast home-to-remote
Switch:1(config-isis)#multi-area ip redistribute unicast home-to-remote route-map test
Switch:1(config-isis)#multi-area ip redistribute unicast home-to-remote enable
Switch:1(config-isis)#show isis multi-area ip redistribute home-to-remote
