4. Enter ROUTER BGP mode.
CONFIGURATION mode
router bgp as-number
5. Use a configured AS-PATH ACL for route filtering and manipulation.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | ipv6-address | peer-group-name} filter-list as-path-name {in |
out}
If you assign an non-existent or empty AS-PATH ACL, the software allows all routes.
To view all BGP path attributes in the BGP database, use the show ip bgp paths command in EXEC Privilege mode.

Filtering Routes with Community Lists
To use an IP community list or IP extended community list to filter routes, you must apply a match community filter to a route
map and then apply that route map to a BGP neighbor or peer group.
1. Enter the ROUTE-MAP mode and assign a name to a route map.
CONFIGURATION mode
route-map map-name [permit | deny] [sequence-number]
2. Configure a match filter for all routes meeting the criteria in the IP community or IP extended community list.
CONFIG-ROUTE-MAP mode
match {community community-list-name [exact] | extcommunity extcommunity-list-name
[exact]}
3. Return to CONFIGURATION mode.
CONFIG-ROUTE-MAP mode
exit
4. Enter ROUTER BGP mode.
CONFIGURATION mode
router bgp as-number
AS-number: 0 to 65535 (2-Byte) or 1 to 4294967295 (4-Byte) or 0.1 to 65535.65535 (Dotted format)
5. Apply the route map to the neighbor or peer groups incoming or outgoing routes.
CONFIG-ROUTER-BGP mode
neighbor {ip-address | ipv6-address | peer-group-name} route-map map-name {in | out}
