I have the folowing sceenario:
1 Cisco Router
2 Different providers, each one providing me a different IP block.
I'm trying to force packets from network A to leave and return via provider A, and packets from network B do leave and return via provider B.
right now, having a default route on the cisco, all packets leave using that default route (provider A), the return is ok, witch makes sense, once the packet reaches destination, will return via the appropiate carrier. The problem is that I got a warning stating that each provider will start blocking the other's packets soon, so I need to send the packets via the appropiate route.
I have tried several configurations, but haven't been able to do so. Help is appreciated.
