www.dell.com | support.dell.com If you want to remove or add a specific COMMUNITY number from a BGP path, you must create a route map with one or both of the following statements in the route map. Then apply that route map to a BGP neighbor or peer group. Use these commands in the following sequence, starting in the CONFIGURATION mode: Step Command Syntax 1 route-map map-name [permit | deny] [sequence-number] 2 set comm-list community-list-name delete set community {community-number | local-as | no-advertise | no-export | none} Command Mode CONFIGURATION CONFIG-ROUTE-MAP CONFIG-ROUTE-MAP 3 exit CONFIG-ROUTE-MAP 4 router bgp as-number CONFIGURATION 5 neighbor {ip-address | CONFIG-ROUTER-BGP peer-group-name} route-map map-name {in | out} Purpose Enter the ROUTE-MAP mode and assign a name to a route map. Configure a set filter to delete all COMMUNITY numbers in the IP Community list. Configure a Community list by denying or permitting specific community numbers or types of community • community-number: use AA:NN format where AA is the AS number (2 or 4 Bytes) and NN is a value specific to that autonomous system. • local-AS: routes with the COMMUNITY attribute of NO_EXPORT_SUBCONFED and are not sent to EBGP peers. • no-advertise: routes with the COMMUNITY attribute of NO_ADVERTISE and are not advertised. • no-export: routes with the COMMUNITY attribute of NO_EXPORT. • none: remove the COMMUNITY attribute. • additive: add the communities to already existing communities. Return to the CONFIGURATION mode. Enter the ROUTER BGP mode. Apply the route map to the neighbor or peer group's incoming or outgoing routes. To view the BGP configuration, use the show config command in CONFIGURATION ROUTER BGP mode. To view a route map configuration, use the show route-map command in EXEC Privilege mode. Use the show ip bgp community command in EXEC Privilege mode to view BGP routes matching a certain community number or pre-defined BGP community.
