Here's a small diagram of a portion of a network.
Right now, I have OSPF routing enabled throughout the entire network, and all the links pictured are in the same area. All traffic from the main datacenter rides the 9MB MPLS pipe. The T1 from the main datacenter to the DR datacenter sits idle at this time and herein is where the problem lies.
The DR datacenter is also one of our branches we conduct business in, and we have workstations on the 1.2.1.0/24 network. The servers in the DR Datacenter are on the 1.2.2.0/24 network. When the 9MB pipe is congested with SAN or IBM iSeries replication traffic, we can experience some slowdown on our workstations.
I've been going over ways to get workstation traffic (1.2.1.0/24
1.1.1.0/24) to traverse the lone T1, and DR Replication traffic (1.2.2.0/24 1.1.1.0/24) to traverse the 9MB pipe.I thought of using policy routing on both the 2611 and the 7206, but then the 7206 would send all traffic sourced from 1.1.1.0 to the next hop, which would be specified as the 2611XM. I also tried increasing the OSPF cost on the F0/0 Ethernet Interface to 65534, thinking that by making this a higher cost, the T1 would then be perferred and this didn't work either.
Am I on the right track or can this not be done?
