Command History
Usage Guidelines You must have a match clause in a route map (even if it points to a “permit everything” list) if you want
to use set commands.
The set commands specify the set actions to be performed when all of the match criteria of a route map
are met. When all match criteria are met, all set actions are performed.
This command requires the LAN Enterprise Services license.
Examples This example shows how to configure a route map that sets the extended community to 1.5:
switch# configure terminal
switch(config)# route-map test1 10 permit
switch(config-route-map)# match as-path 1
switch(config-route-map)# set extcommunity generic transitive 1.5
none (Optional) Specifies the no community attribute.
generic Specifies the generic specific extended community type.
transitive Configures BGP to propagate the extended community attributes to other
autonomous systems.
nontransitive Configures BGP to propagate the extended community attributes to other
autonomous systems.
aa4:nn (Optional) Autonomous system number and network number. This value is
configured with a 4-byte AS number and a 2-byte network number
separated by a colon. The 4-byte AS number range is from 1 to 4294967295
in plaintext notation, or from 1.0 to 56636.65535 in AS.dot notation. You
can enter a single community or multiple communities, each separated by a
space.
additive (Optional) Adds to existing community.
