Configuring Policy Basd Routing
Posted on 2014-10-04
As you can see in the diagram attached below, I have four links between two of my sites. Two links are 10 Mbps capacity each and I am equally load balancing my traffic between them. Two more links are there of 200 Mbps capacity each and I am using them in active/standby state i.e. if one of the link goes down then the traffic is shifted to the other 200 Mbps link. All the links are L3 links.
Currently I am using EIGRP only to route the traffic between both the sites on both the 10 Mbps links. I have configured specific static routes to use the 200 Mbps link only when the traffic is between 126.96.36.199/24 and 188.8.131.52/24 Servers.
Now I want to configure routing using all the links in EIGRP in such a way that the two 10 Mbps links work in equal load balancing, the 200 Mbps links should work in active/standby mode i.e. traffic should shift to secondary 200 Mbps link only in case the primary link goes down.
Any traffic with the destination of 184.108.40.206/24 servers should use the active 200 Mbps link and when the traffic is being generated/replied from 220.127.116.11/24 network should use the 200 Mbps active link. The traffic sourced/destined for Y.Y.Y.Y/Y network should use the 10 Mbps links only.
Thanks in advance
