RIPv2 same hop count config

Hello,

We have a customer that has a fiber rum between 2 building. They want to have 2 seperate fibers active that terminate into the same switch on each end. (redundancy).

In building A they have an extreme networks black diamond switch that does not support STP.

In bulding B they have a Cisco 4507.

We will ahve to use a layer 3 routed connection due to the fact their switch in building A does not support STP.

Our tech does not want to use static route becuase he does not want to setup IP SLA for the redundant connection.

Will RIPv2 work for this scenario and failover to the other fiber if needed? The hop count is the same for each fiber path....

Let me know if you have question.untitled.bmp

I would say that it would work. Since they're the same hop count, you're going to have equal cost routes in the routing table. If you only want 1 route in the table and then want to fail over to the other route in case of a failure, you could apply an offset list in rip to modify the metric for the less preferred route. Then when the more preferred drops out, you'd fail over to the other.

HTH,

Hi,

why not just bundle the interfaces at L2 ?
