command executed, the router sends a default route with the
next hop being itself to the specified MBGP peer or peer group, regardless of whether the default route
is available in the routing table.
Configuring Outbound MBGP Route Filtering
If several filtering policies are configured, they are applied in the following sequence:
z
filter-policy export
z
peer filter-policy export
z
peer as-path-acl export
z
peer ip-prefix export
z
peer route-policy export
Only the routes that have passed all the configured policies can be advertised.
