OSPF path selection ??
Question:
I have the below topology Catalyst 3560 Price in my network I am planing to configure ospf in my network .
Can any one confirm that how traffic will flow from B router to reach the networks behind the a router .
with default ospf configurations .
will it take the directly connected link to reach the router A 's network network ? or will it go through router C to reach the router A ?
Answer:
If you have default OSPF configuration. It will do load balance.
Cost of link connecting Router-A and Router-B = 10^8/1mb = 100
Cost of link connecting Router-B and Router-C = 10^8/2mb = 50
Cost of link connecting Router-C and Router-A = 10^8/2mb = 50
So router B is having two equal Catalyst 3560V2 Price cost path to reach A.
