Level 1

Good, Best Regards,

I appeal to you to help me to my next question

I have 3 Cisco 7200 router, IOS 12.2 all interconnected by links pto pto.

Router 1 to Router 2

Router 1 on router 3

Router 2 to router 1

Router 2 to router 3

Router 3 Router 1

Router 3 Router 2

I need that a CIDR of addressed  /24  always take router -- "Route 3 to Router 1" and return the same,l based only if your destination address is X.X.X.X

isis used as routing protocol

Do I use PBR?

Thanks,

Ingrid

If your destination address is going a different direction than your route in the routing table, you'll need to configure pbr. For example, if you have a host at 1.1.1.1 and you want it go to R2 - R1 from R3, but you have 1.1.1.0/24 on R3 that points to R1, you would need pbr to force the traffic to R2 first and override the routing table.
