Policy-based routing

Policy-based routing (PBR) provides a mechanism to redirect IPv4 and IPv6 data packets based on the policies defined to override the switch’s forwarding decisions based on the routing table.

Policy-based route-maps

A route-map is an ordered set of rules that control the redistribution of IP routes into a protocol domain. When you enable PBR on an interface, all IPv4 or IPv6 data packets received are processed based on the policies that you define in the route-maps. The rules defined in the route-maps are based on access control lists (ACLs) and next-hop addresses, and only apply to ACLs used in policy-based routing.

You can create a route-map that specifies the match criteria and the resulting action if all the match clauses are met. After you create the route-map, you can enable PBR for that route-map on a specific interface. Route-maps contain match and set statements that you can mark as permit.
