Which metric is used for OSPF?
Hop Limit
Auto cost reference bandwidth
PFM
Latency
According to Cisco (http://www.cisco.com/c/en/us/support/docs/ip/open-shortest-path-first-ospf/7039-1.html) OSPF, there is no limitation on the hop count ⢠The intelligent use of VLSM is very useful in IP address allocation. ⢠OSPF uses IP multicast to send link-state updates. This ensures less processing on routers that are not listening to OSPF packets. Also, updates are only sent in case routing changes occur instead of periodically. This ensures a better use of ****bandwidth**** Hop and Hop limits refers to RIP (Rest in Peace since OSPF is faster on convergence - remember that)
