Configuring OSPF inbound route filtering

•
Filters routing information by next hop through the filtering criteria configured with the gateway
keyword.
•
Filters routing information by destination address through ACLs and IP address prefixes and by
next hop through the filtering criteria configured with the gateway keyword.
•
Filters routing information by routing policy specified by the route-policy keyword.
For more information about IP prefix list and routing policy, see "Configuring routing policies."
