Multiple WAN links and routers for redundancy
Posted on 2008-10-20
Hi, I'm working for a company and we want to employ an additional WAN link with a seperate provider, for redundancy purposes, along with a seperate router for each link.
My question is: each router, I guess, I will have its own internal and external IP address. Is there a way that this can be configured so that each router will automatically pickup the load if one fails? Or can they be used for load balancing?
I'm sure this can be done, but how? If each client is using the IP address for the default gateway of say, the first router, then if this router or the link it's connected to fails, then how will the clients redirect automatically to the second router?
I would want to use Cisco kit ideally, is there some Cisco IOS features that can do this? Thanks.
