About MAX hop count
|

| Did some research on maximum hop counts on routing protocols,
RIP: 15
IGRP: 255(default100)
EIGRP: 255(default100)
OSPF: 100
However, just saw in a book that,
it is wrong EIGRP has a max hop count of 255.
OSPF don't have max hop limits.
I'm so confused..
anyone knows about it?
THanks!!! | |

| Routing protocols assign costs to routes (route metrics). In RIP, the cost of a route is the hop count to reach the destination. I know for a fact that OSPF does not use hop counts in computing costs. I think neither IGRP, nor EIGRP use hop counts. | |

| I know that OSPF use cost, which is based on bandwidth as metric, and igrp/eigrp use bandwidth, delay, MTU, reliability, load as metric(default only the first two). However, hop limits here may only be related to topology, adn lot of resources mentioned max hop limits...

| IGRP/EIGRP don't use hop count as part of the metric as damftei says, but I think it is a TTL feature.
