Policy routing PBR

Policy routing experimental environment GNS3 policy routing: better than the routing table, more flexible, can specify the next-hop forwarding address, has a stronger control. Specific other online search, a lot. I won't explain it in detail.

Experimental procedure

Step 1: set each IP address and refer to a default route to R3 on R1Magic R2 and R4 respectively (there is no route entry on R3)

Ip route 0.0.0.0 0.0.0.0 23.1.1.3

Step 2: set ACL on R3, catch the entry, and let the entry go straight to the next hop

Route-map aa permit 10

Match ip address 10

Set ip next-hop 34.1.1.4

Route-map bb permit 10

Match ip address 20

Set ip next-hop 34.1.1.4

Int f0/0

Ip policy route-map aa (configured in the interface)

Int f0/1

Ip policy route-map bb

Access-list 10 permit 13.1.1.0 0.0.0.255

Access-list 20 permit 23.1.1.0 0.0.0.255

The experiment is relatively simple, but not only this way of play, there are a lot of fun waiting for us to dig.
