I just got in an argument with my colleague.
This is the senario:
We have to 2 Cisco GSR routers, that connect to 2 7609 Internet Routers in a FULL MESH topology all running ISIS as metric of 6 as our IGP.
The GSR's then point to another autonomous system running only eBGP.
Now, my colleague is insisting that in the FULL MESH topology we have (listed above)..
To achieve proper "traffic balance", meaning that taffic flows evenly through all links.. load balances...
You need to have the nieghorships on the physical links and not pointing to the loopbacks..
Is this correct..??
I am under the impression that:
If you have ISIS properly configured with equal metrics you will achieve load balancing and traffic will flow evenly across all links... And you the neighborships are done with the loopbacks..
Who is correct... I think I am...
