Enabling IPv6 IS-IS MT

You can enable IPv6 IS-IS MT in an area or a domain so that the MT-enabled devices runs IPv6 IS-IS in multi SPF mode. The following task enables IPv6 IS-IS MT with transition support.

Procedure

  1. Enter the configure terminal command to access global configuration mode.
    device# configure terminal
  2. Enter the router isis command to enter IS-IS router configuration mode and enable IS-IS on the device.
    device(config)# router isis
    
  3. Enter the address-family ipv6 unicast command to enable ISIS address-family IPv6 unicast configuration mode.
    device(config-isis-router)# address-family ipv6 unicast
    
  4. Enter the multi-topology command with the transition parameter to enable IPv6 IS-IS MT with transition support.
    device(config-router-isis-ipv6u)# multi-topology transition
    

Example

The following example enables IPv6 IS-IS MT with transition support.

device# configure terminal
device(config)# router isis
device(config-isis-router)# address-family ipv6 unicast
device(config-router-isis-ipv6u)# multi-topology transition
