We have a large (and getting bigger rapidly) corporate WAN with lots of 
divisional LANS hanging off it.

At present we run RIP everywhere to distribute routing information, but
are now considering IGRP and OSPF as an alternative, more robust set of
routing protocols to handle IP routing on the WAN.

We have a Class B net address (134.18) and use a class C mask across all sites
for our subnets. As I understand it IGRP cannot redistribute RIP routing 
information for subnets (is this true for the latest versions of the router 
code??). This presents a problem since within several of the end LANs, 
there exist several subnets that use workstations with multiple interfaces
running routed/gated to gateway between the subnets at that site.

We also connect to the Internet which also mandates RIP. Can we have RIP
turned on for the interface that connects us to the outside world but use 
IGRP internally (this is an AGS+)??

What alternatives, pros/cons confront us??

a) Static routing tables in our RIP only workstations (ie. turn off rip).

b) connect all subnets in the LANS to the WANS via a cisco ie. don't use the
   workstations to do the routing.

c) I seem to recall the latest version (still under test?) of gated supports
   OSPF. Maybe this could be ported to the UNIX machines currently doing
   the routing and run OSPF internally.

c) do nothing

There are no doubt lots of other scenarios to choose from.

All help will be gladly received :)
