Differents between OSPF & EIGRP

1)Ospf is open standard and EIGRP is cisco propreitary.

2)Administrative distance for OSPF is 110 and for EIGRP AD is 100.

3)Ospf uses Cost as the metric values to calculate the shortest path wheres as EIGRP used 5 metric values

(Bandwidth,Delay,Load,MTU & Reliablity) to calculate the shortest path.

4)There is no hop count limitations in the OSPF, there is hop count limitations in EIGRP. I think it supports

maximum of 255 hopcounts in EIGRP.

5)In OSPF, there is no Backup route options, wheres as in EIGRP it will maintain Backup route. So if main link goes down, it will directly take the backup route and starts working, where as in OSPF, if main route fails

it has to recalculate the shortest path.
