Metric Hop Count Hop Count
Metric (24 bit) : Composite Metric (BW+Delay+Load+MTU+Reliability)
Metric (32 bit) : Composite Metric (BW+Delay+Load+MTU+Reliability)
Metric = Cost =108/Bandwidth in bps (CISCO)
Hop Count Max 15, Routers - 16 Max 15, Routers - 16 Max Hop count is 255 (100 is default)
Max Hop count is 255 (100 by default)
