Hey everyone, I am looking for a solution to a routing decision problem. Maybe I have been doing this "the old way" so long I just can't see any other options.... so I'd thought I'd reach out and ask everyone for input.
I have 4 sites, fully meshed via GRE tunnels. I use EIGRP now. I need routing decisions to be based on lowest latency path, and not lowest hop count. I have a latency sensitive app, that runs between all sites and sometimes a 2 hop path has less total latency then the direct 1 hop path. EIGRP continues to use the direct path. For example, the 2 hop path equals 8ms while the 1 hop path is 20ms.
Can I use EIGRP to make that decision real time? Other protocols?
I understand that EIGRP is using bw and delay. BW is set equal on the tunnels and delay varies but not enough to make the decision to use the 2hop, lower latency path?
Any thoughts on the matter?
Thanks in advance.
