Specifying a priority for IS-IS
A router may run multiple routing protocols. When routes to the same destination are found by multiple
routing protocols, the route learned by the protocol with the highest priority wins. You can reference a
routing policy to specify a priority for specific routes. For information about routing policy, see the
chapter “Configuration routing policies.”

efficiency.
To configure the maximum number of equal cost routes:
Step Command
1. Enter system view. system-view
2. Enter IS-IS view. isis [ process-id ] [ vpn-instance vpn-instance-name ]
