Specifying A Priority For Is; Configuring The Maximum Number Of Equal Cost Routes; Configuring Is-Is Route Summarization - H3C S5500-EI Configuration Manual

To do...
Configure a bandwidth

IS-IS cost calculation
Specifying a priority for IS-IS
A router can 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 can be adopted. You can
reference a routing policy to specify a priority for specific routes. For information about routing policy,
see the chapter "Routing policy configuration."
Follow these steps to configure the priority of IS-IS.
To do...
Enter system view
Enter IS-IS view
Specify a priority for IS-IS

Configuring the maximum number of equal cost routes

If multiple equal cost routes reach the same destination, the traffic can be load balanced to enhance
efficiency.
Follow these steps to configure the maximum number of equal cost routes:
To do...
Enter system view
Enter IS-IS view
Specify the maximum number of
equal cost routes for load
balancing

Configuring IS-IS route summarization

This task allows you to configure a summary route so routes falling into the network range of the summary
route are summarized into one route for advertisement. Doing so can reduce the size of routing tables, as
well as the scale of LSP and LSDB. Both IS-IS routes and redistributed routes can be summarized.
