Although Zebra is probably the way of the future, you may want to look at gateD for now. Its bgp and ospf has been quite reliable for us. Its features are sparse, but it might have all that you need. With two full views, you want more than 128M of RAM if you really are going to install 70K+ routes in the kernel routing table. 196 is fine, but with the cost of RAM these days, you might as well throw in 256MB. With a decent Celeron (433 is fine), you can get some pretty OK convergence times. On one of my borders, I push about ~15Mb/s though 4 ethernet interfaces with a dozen ipfw filter rules. ---Mike Mike Tancsa (mdtancsa@sentex.net) Sentex Communications Corp, Waterloo, Ontario, Canada "Given enough time, 100 monkeys on 100 routers could setup a national IP network."
