Parameters

all

Causes all (up to a maximum of 16) routes to be advertised.

best num

Specifies the number of best routes to advertise.

best-range

Causes advertisement of routes within a number range.

start-num: Specifies the start number of the range of routes to advertise. The number ranges from 1 through 16.
end-num: Specifies the end number of the range of routes to advertise. The number ranges from 1 through 16.

Route-map configuration mode

Usage Guidelines

A match occurs when an additional path that is a candidate for advertisement has the same path marking (tag) as the marking configured by using the match additional-paths advertise-set command.

Only one match additional-paths advertise-set command configuration is allowed for each route map; any subsequent match additional-paths advertise-set command configuration overwrites the previous configuration.

The no form of the command restores the default configuration.

Examples

The following example shows how to configure route map (rm_example) to advertise the group-best route.

device# configure terminal
device(config)# route-map rm_example permit 123
device(config-routemap-rm_example/permit/123)# match additional-paths advertise-set group-best
