Operation Command Description
Enable default route
advertising
peer group-name
default-route-advertise
[ route-policy
route-policy-name ]
Required
By default, a BPG router
does not send default
routes to a specified
peer/peer group.
 Note:
With the peer default-route-advertise command executed, no matter whether the
default route is in the local routing table or not, a BGP router sends a default route,
whose next hop address is the local address, to the specified peer or peer group.
5.4.5 Configuring Related ACLs
Two types of BGP-specific access control list (ACL) exist: AS path filtering ACL and
community attribute ACL.
AS path filtering list filters routing information by the AS_Path attribute of BGP route.
Community attribute list is a list identifying a community message. Community attribute
lists fall into two categories: standard community access control list and extended
community access control list.
