676BConfiguring the maximum number of ECMP routes
Perform this task to implement load sharing over ECMP routes.
To configure the maximum number of ECMP routes:

Command Remarks
351. Enter system view. system-view N/A
352. Enter IS-IS view.
isis [ process-id ] [ vpn-instance
vpn-instance-name ]

353. Specify the maximum number
of ECMP routes.
maximum load-balancing number
By default, the maximum
number of ECMP routes is 8.
677BConfiguring IS-IS route summarization
Perform this task to summarize specific routes, including IS-IS routes and redistributed routes, into a single
route. Route summarization can reduce the routing table size and the LSDB scale.
Route summarizes applies only to the locally generated LSPs. The cost of the summary route is the lowest
one among the costs of more-specific routes.
To configure route summarization:

Command Remarks
354. Enter system view.
system-view N/A
355. Enter IS-IS view.
isis [ process-id ] [ vpn-instance vpn-instance-name ] N/A
356. Configure IS-IS route
summarization.
summary ip-address { mask | mask-length }
[ avoid-feedback | generate_null0_route | [ level-1 |
level-1-2 | level-2 | tag tag ] *
By default, route
summarization is not
configured.
678BAdvertising a default route
IS-IS cannot redistribute a default route to its neighbors. This task enables IS-IS to advertise a default route
of 0.0.0.0/0 in an LSP to the same-level neighbors. Upon receiving the default route, the neighbors add
it into their routing table.
You can use a routing policy to generate the default route only when the routing policy is matched by a
route entry in the routing table.
To advertise a default route:
