==========================================================

In the event of a network failure EIGRP remembers available backup routes and fails over almost immediately, where as OSPF needs to re-run the SPF algorithm to find any "backup" routes which results in extra processor cycles.

EIGRP cuts out processor cycles by learning only the best routes from its neighbors (routing by rumor) and because of this it does not have an entire view of all the paths to all the networks, it rather has a view of the network based on its neighbors view.  OSPF neighbors send all info to the DR and BDR which then update all of the other neighbors in the area.  This results in all OSFP routers in the area knowing about all the paths to all the networks at the same time and all routers in the area have the exact same view of the entire network.

With OSPF you would need to limit each area to 500 Routers (I think…please check that figure) due to the overhead of the SPF algorithm.  I don’t think EIGRP suffers from a limitation to the amount of routers you can place…this one I am not 100% about (Perhaps one of the CCIE’s could comment on this point).


EIGRP is Cisco proprietary where as OSPF is industry standard and plays nicely with other vendor routers.

In EIGRP you can summarize networks on any EIGRP router in the network however with OSPF you can only perform summarization on the ABR and ASBR routers.

EIGRP supports un-equal load balancing where as OSPF does not.

EIGRP (Distance vector) like RIP has the ability to turn off the auto-summary feature which advertizes networks at their classfull boundary by default.  OSPF does not advertize networks at their classfull boundary, nor does it have the ability to turn this feature on.
