Applying a Routing Policy to Routing Protocols
You can apply the following routing policy elements to a routing protocol:
- Routing policy—You can apply a single routing policy to a routing protocol.
- Chain of routing policies—You can apply multiple routing policies (chains) to a routing protocol.
- Policy expression—You can apply a policy expression to a routing protocol. A policy expression uses Boolean logical operators with a routing policy and routing policy chains. The logical operators establish rules by which the policy or chains are evaluated.
