The switch supports the use of the following interior gateway protocols (IGPs):
RIP is a distance-vector protocol, based on the Bellman-Ford (or distance-vector) algorithm. The distance-vector algorithm has been in use for many years and is widely deployed and understood.
OSPF and IS-IS are link-state protocols, based on the Dijkstra link-state algorithm. OSPF and IS-IS are newer IGPs and solve a number of problems associated with using RIP on today‘s complex networks.
NoteRIP can be enabled on a VLAN with either OSPF or IS-IS. OSPF and IS-IS cannot be enabled on the same VLAN.
