Filtering BGP Routes Using AS-PATH
Information
To filter routes based on AS-PATH information, use these commands.
1
Create a AS-PATH ACL and assign it a name.
CONFIGURATION mode
ip as-path access-list
as-path-name
2 Create a AS-PATH ACL filter with a deny or permit action.
AS-PATH ACL mode
{deny | permit}
as-regular-expression
3 Return to CONFIGURATION mode.
AS-PATH ACL
exit
4 Enter ROUTER BGP mode.
CONFIGURATION mode
router bgp
as-number
5 Filter routes based on the criteria in the configured route map.
CONFIG-ROUTER-BGP mode
neighbor {
ip-address
|
peer-group-name
} filter-list
as-path-name
{in | out}
Configure the following parameters:
•
ip-address
or
peer-group-name
: enter the neighbor’s IP address or the peer group’s name.
•
as-path-name
: enter the name of a configured AS-PATH ACL.
•
in
: apply the AS-PATH ACL map to inbound routes.
•
out
: apply the AS-PATH ACL to outbound routes.
To view which commands are configured, use the
show config
command in CONFIGURATION ROUTER
BGP mode and the
show ip as-path-access-list
command in EXEC Privilege mode.
To forward all routes not meeting the AS-PATH ACL criteria, include the
permit .*
filter in your AS-PATH ACL.
