I have the following problem:
There are two separate DC's with a separate ACI fabric running in each DC. Any traffic (such as data, heartbeat, replication, etc) between the two DC's goes over a SDH/DWDM via EoMPLS. Any congestion or failure on the local link can cause failures on heartbeat traffic which is very critical. I want to know how I can separate the data traffic from the critical heartbeat traffic - basically keeping the data traffic on the existing EoMPLS and having the heartbeat traffic go over a separate local link via the same DWDM. Can I utilize OTV or VXLAN? What about using ACI multi-pod or multi-site?
Looking for some help and recommendations to steer me in the right direction. Any links to documentation would be appreciated.
