I've got a router on Mae West with an open peering policy that has
close to 70 peers. I'm currently running gated on a P133 box and have
just increased the size of data structures as the number of peers
grew. We are looking at going to a Cisco 7200 (with NPE200) or 7500
(with RSP4), but I haven't been able to determine weather these
routers will handle this many peers and still have room for expansion.
I've heard that Cisco IOS has a software limit, even if the RSPs can
handle it, but I haven't been able to tell what it was. Are there
routers from other vendors out there handling large numbers of peers?
Our bandwidth is too low to want to consider putting a second router
on the NAP. I've considered providing ebgp multihop peering to other
routers behind this one, but I haven't heard of others doing this sort
of thing on the NAP's before. Of course, there are the route servers,
but I'm more interested in offering direct peering to anyone that
I only have full routing tables coming in at 2 places in my network
and might anticipate having 8 - 10 IBGP peer sessions in addition to
