- Standard IP route forwarding is based off of destination and next hop.
- Policy Based Routing:
- Can be based off of multiple criteria, such as source, destination, protocol type, and source interface.
- In Cisco this is matched with a route map.
- Permit uses policy routing and deny uses normal routing table forwarding.
- Action defines what the policy is doing.
- ‘debug ip policy’ can be used to verify and troubleshoot.
- Can be applied with incoming and locally originated traffic.
