Configuring The Maximum Number Of Ecmp Routes; Configuring Is-Is Route Summarization; Advertising A Default Route - HP MSR2000 series Configuration Manual

To configure the priority of IS-IS:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify a priority for IS-IS.

Configuring the maximum number of ECMP routes

Perform this task to implement load sharing over ECMP routes.
To configure the maximum number of ECMP routes:
Step
1. Enter system view.
2. Enter IS-IS view.
3. Specify the maximum number
of ECMP 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.
The router summarizes only the routes in the locally generated LSPs. The cost of the summary route is the
lowest one among the costs of summarized routes.
To configure route summarization:
Step
1. Enter system
view.
2. Enter IS-IS view.
3. Configure IS-IS
route
summarization.

Advertising a default route

A router running IS-IS cannot redistribute any default routes or advertise a default route to neighbors. Use
the following commands to advertise a default route of 0.0.0.0/0 to the same level neighbors.
