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. Optional: Disable the transmission of route tags in Multi-area SPB:
    multi-area ip redistribute unicast delete-tags
  5. Enable the Multi-area SPB IPv4 unicast redistribution instance:

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

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

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

  7. 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

Variable Definitions

The following table defines parameters for the multi-area ip redistribute unicast and the isis multi-area ip apply redistribute unicast commands.

Variable Value
delete-tags Disables the transmission of route tags in Multi-area SPB. Use this parameter if platforms do not correctly calculate the TLV length in TLV 135. By default, route tags are transported in Multi-area SPB.
enable

Enables Multi-area SPB IPv4 unicast redistribution.
home-to-remote

Specifies the IPv4 unicast redistribution configuration for home to remote direction.
remote-to-home

Specifies the IPv4 unicast redistribution configuration for remote to home direction.
route-map WORD<1-64>

Specifies the name of the route policy.
vrf WORD<1-16>
