Routing Protocol!

Let's say I am the administrator of a HUGE network, with tens of thousands of users, with a few hundred routers in a sort of a mesh like topology. What would be a routing protocol that could handle frequent updates, under a heavy traffic load?

OSPF, but you might need more routers, as you'll need a large processing overhead if lots of requests are being made at once.

 

IS-IS would also work, or the standard old school protocols like RIP or EIGRP if you're using Cisco routers.

OSPF sounds good. I was trying to avoid RIP, as it updates every 30 seconds, all the time, I don't know if OSPF, IS-IS, or EIGRP does. I thought OSPF updated on a as-needed basis, which would minimize traffic. RIP is also limited to 15 hops. Would BGP be appropriate?
