Configuring BGP route filtering policies
Configuration prerequisites
Before you configure BGP routing filtering policies, configure the following filters used for route filtering
as needed:
•
ACL (see
ACL and QoS Configuration Guide
)
•
Prefix list (see "
Configuring routing policies
")
•
Routing policy (see "
Configuring routing policies
")
•
AS path list (see "
Configuring routing policies
")
Configuring BGP route distribution filtering policies
To configure BGP route distribution filtering policies, use the following methods:
•
Use an ACL or prefix list to filter routing information advertised to all peers.
•
Use a routing policy, ACL, AS path list, or prefix list to filter routing information advertised to a peer
or peer group.
If you configure multiple filtering policies, apply them in the following sequence:
1.
filter-policy export
2.
peer filter-policy export
3.
peer as-path-acl export
4.
peer prefix-list export
5.
peer route-policy export
Only routes passing all the configured policies can be advertised.
To configure BGP route distribution filtering policies (IPv4 unicast/multicast address family):
