Match Community - Allied Telesis SwitchBlade x908 Series Software Reference Manual

Route Map Commands

match community

Use this command to add a community match clause to a route map entry. Specify the
community value or values to match by specifying a community list. To create the community
list, enter Global Configuration mode and use the ip community-list command.
A BGP update message matches the route map if its attributes include community values that
match the community list.
Each entry of a route map can only match against one community list in one community match
clause. If the route map entry already has a community match clause, entering this command
replaces that match clause with the new clause.
Note that community lists and route map entries both specify an action of deny or permit. The
action in the community list determines whether the route map checks update messages for a
given community value. The route map action and its set clauses determine what the route
map does with update messages that contain that community value.
Use the no parameter to remove the community match clause from a route map.
