7.18.2 Enabling Multi-Topology for IPv6 IS-IS Processes

Based on service requirements and network planning, you can associate IS-IS processes with
multiple different topology instances. In this manner, an IS-IS AS can be divided into multiple
logical topologies.
Context
After enabling multi-topology for IS-IS, configure parameters, such as interface costs and
protocol priorities, for IS-IS topology instances.
The parameters configured in the IS-IS topology view are valid only for the specified IS-IS
topology instance. This allows you to configure different parameters for different IS-IS topology
instances.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
isis [ process-id ]
The IS-IS view is displayed.
Step 3 Run:
cost-style { narrow | wide | wide-compatible }
The cost style for the packets received and sent by the router is set to wide or wide-
compatible.
Step 4 Run:
ipv6 topology topology-name [ topology-id { multicast | topology-id } ]
The specified IS-IS process is associated with the specified topology instance, and the IPv6 IS-
IS topology view is displayed.
