PBR (Policy Based Routing)

Policy Based Routing

1.) Override the instruction of the routing table using PBR
2.) Specific traffic to be routed differently from the routing table, maybe for security reasons,
performance reasons or some sort of structure design reasons.

Example: Manipulate route of host to go over
ISP2 if going to host

STEP1 Create ACL

Router(config)#ip access-list extended ACL-PBR
Router(config-ext-nacl)#permit ip host host

STEP2 Create Route-Map

Router(config)#route-map PBR
Router(config-route-map)#match ip address ACL-PBR
Router(config-route-map)#set ip next-hop

STEP3 Create Policy (Local PBR)

Router(config)#int e0/2
Router(config-if)#ip policy route-map PBR

Trace route from PC1 to Server
