available in the routing table.
Configuring outbound MBGP route filtering
If several filtering policies are configured, they are applied in the following sequence:
•
filter-policy export
•
peer filter-policy export
•
peer as-path-acl export
•
peer ip-prefix export
•
peer route-policy export
Only the routes that have passed all the configured policies can be advertised.
Follow these steps to configure BGP route distribution filtering policies:

At least one of these approaches
is required. No outbound route
filtering is configured by default.
