Route policies

Route policies are a Nortel proprietary improvement on existing routing schemes. Using existing routing schemes, packets are forwarded based on routes that have been learned by the router through routing protocols such as RIP and OSPF or through the introduction of static routes. Route policies introduce the ability to forward packets based on rule sets created by the network administrator. These rule sets, or policies, are then applied to the learned or static routes.

Route policies on the Nortel Ethernet Routing Switch 5500 Series supports the Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) protocol. When used in conjunction with these protocols, route policies can be used to perform the following tasks that are not possible using traditional routing methods:

•Listen for routing updates from specific gateways.

•Listen for routing updates from specific networks.

•Assign a specific subnet mask to be included with a network in the routing table.

•Advertise routing updates from specific gateways.

•Advertise routing updates to specific networks.

•Assign a specific subnet mask to be included in the route summary packets.

•Advertise routes learned by one protocol to another.
