Route Map - Avaya 1000 Series Configuration Manual

View the routes that have the community value of 10. In this case it should be just the route
18.1.0.0/21:
Avaya2> show ip bgp community aa_nn 0:100
Avaya2> show ip bgp community number 100
The above output shows that 18.1.0.0/21 has a community value of 100 set to it. Avaya has
two ways of displaying the communities. Either by just giving a community number value or
in a x:x notation like 0:100. Both give the same results.

Route Map

Route maps are used to match and modify certain routing information. A Match can be done
on one of the following:
• as_path > match BGP AS path list
• community > match BGP community list
• ip > ip specific information
One a Match is done, the following attributes can be set on those matched information:
• as_path > prepend string for a BGP AS-path attribute
• commit > commit configuration
• community > bgp community attribute
• distance > BGP preference path attribute
• local_preference > BGP local preference path attribute
• metric > Metric value for destination routing protocol
• metric_type > metric type for destination routing protocol
• origin > bgp origin code
Create a route_map by name AS-200Filter and apply it to neighbor Avaya2. The route_map
AS-200Filter has a sequence number of 100 which has a condition that denies everything that
matches the ip access list 10.
Avaya1/configure> policy route_map AS-200Filter 100
deny
Avaya1/configure/policy/route_map AS-200Filter 100>
match ip ip_address 10
Issue a show command to verify the routemap and ip_access list:
Avaya1/configure> show policy route_map
route-map AS-200Filter, deny, sequence 100
Match clauses:
ip-address (ip-access-list filter): 10
Set clauses:
