Re: RIP in Operation

We use RIP extensively on the edges of our network to build a Layer3 routed overlay between 3550/3750 switches and our 6500-based core. At $2k/list for the EMI license PER SWITCH ($4k for 3750s), it just wasn't feasible for us to use EMI just for OSPF when all we were really announcing was a loopback and a /30 connected network.

We route filter and tune the RIP times down quite a bit. Meets our needs on the edges.

I assume you mean RIPv2, ie. classless. With that caveat, I can certainly see why RIP would be used. Steinar Haug, Nethelp consulting, sthaug@nethelp.no
