BSR 2000 Configuration and Management Guide
Example
This example uses a community list to filter routes based on the local preference. The
following commands, executed in Global Configuration mode, define a community
list. Specify community list 1 to permit routes from AS 100 and community list 2 to
permit routes from AS 200, as shown in
The next commands, also executed in Global Configuration mode, define the first
instance of the route map with the appropriate match and set clauses and specify route
map 10, instance 10. This permits the route to be accepted and its local preference to
be set to 50. The last command indicates that the route is part of the communities
defined in Community List 1.
The following commands define the second instance of the route map, route map 10
to permit the route to be accepted and its local preference to be set to 25 if the route is
part of the communities defined in Community List 2.
The following commands, executed from Global Configuration mode, enable BGP
and specify an AS. As indicated in
Boston in AS 100. They specify the AS of the BGP neighbors, New York and Miami,
to which the route map applies, and apply the route map 10 for all incoming routes
from router New York and Miami.
It is assumed that the New York and Miami routers set their outgoing routes (to
Boston) to belong to communities 200 and 300, respectively.
