router
Syntax router
Context configure>system>resource-profile
config>system>glob-res-profile
Description
This command enables the context to configure router parameters that is applicable to the entire
chassis (in other words it applies to all IMMs).
ecmp
Syntax ecmp max-routes-dest
no ecmp
Context configure>system>resource-profile>router
config>system>glob-res-profile>router
Description
This command configures the maximum amount of routes of same cost to the same IP destination/
prefix when IP path sharing is enabled using ECMP. To enable optimum usage of hardware resources,
software allocates hardware resources in groups of fixed number of entries. A group is a set of IP
next-hop entries used by ECMP routes. The number of IP next-hop entries per group (which in turn
dictates the maximum number of shared IP paths per IP destination/prefix) is also specified with
commands. Software uses the same group if all the IP next-hop in use for the ECMP routes is the
same.
This command does not enable use of ECMP. To enable ECMP user must use the command
config>router> ecmp. The number of routes specified using the command config>router>ecmp
cannot exceed the number of routes specified by this command, though it can be lesser. If its lesser,
then software will use only the specified number routes. Note though that specifying lesser number of
routes with config>router>ecmp will result in wastage of hardware resources.
NOTES:
Default 1
Parameters
max-routes-dest — The number of ECMP routes.
max-ipv6-routes
Syntax [no] max-ipv6-routes number
