2 reasons an organization would use OSPF - 1. It's a standards-based protocol, which means that you could run any (not just Cisco) OSPF devices in your network and they'll interoperate. 2. It's "controllable", so that you can keep your routing tables smaller by using area routing disadvantages (according to Cisco) of OSPF versus EIGRP is that it uses more CPU I've never worked in the ISP environment, but I'd imagine that they need to use some sort of IGP within their BGP domains, and if they do use an IGP, OSPF would probably be their choice because of the multi-vendor support. ----- Original Message ----- From: David Cooper <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, March 14, 2001 6:30 PM Subject: OSPF > Hey all, > > I've been reading into BSCN here lately with Cisco press books.
