Hello Anoop

Take a look at this post:

OSPF Path Selection explained

Hello Swapnil Both IS-IS and OSPF are link state protocols, and both use the same Dijkstra algorithm to compute the best path through the network. However, they do have a few differences in their architecture. You can read more about the differences here: Specifically concerning scalability, IS-IS does not use as much bandwidth to function as OSPF and its algorithm is less CPU and memory intensive. As stated in the above link, “Given the same set of resources, IS-IS can support more rou…

I hope this has been helpful!
