Configuring Inbound MBGP Route Filtering
By configuring MBGP route reception filtering policies, you can filter out unqualified routes from an
MBGP peer or peer group.
If several filtering policies are configured, they are applied in the following sequence:
z filter-policy import
z peer filter-policy import
z peer as-path-acl import
z peer ip-prefix import
z peer route-policy import
Only the routes that have passed all the configured policies can be advertised.
Follow these steps to configure MBGP route reception filtering policies:
