[c-nsp] which IGRP?

[Jeff Chan]

We're finally adding a third and possibly fourth router to our
small network, and I'm asking for suggestions about which IGRP to
run.  We currently have a 7513/RSP4 as our main router.  It has
our two upstream connections.  We also have a 3640 at a public
peering point hearing routes from a few peers there and
announcing ours to them.  We're using iBGP between the 3640 and
7513, but with a third router, which we would be migrating one
uplink to, it seems we'd need to fully mesh and/or set up a route
reflector if we wanted to continue to use iBGP as our interior
protocol.

Instead of iBGP, should we use a routing protocol optimized
specifically for interior use such as EIGRP, OSPF, etc.?
Or can it be done satisfactorily with iBGP and a route reflector
setup?  (Naturally we're talking eBGP to our external peers.)

Is there a standard practice for this?   IOS is 12.3(13)
mainline everywhere.
