RIP vs OSPF

• RIP eats lots of bandwidth (all broadcast traffic) on large networks. After initialization, OSPF only sends deltas.

• RIP takes 30 – 60 seconds to converge (noticeable downtime). OSPF converges almost immediately, even in large networks.

• RIP doesn't understand netmasks. OSPF groks CIDR.

• RIP sucks. OSPF doesn't.
