What is the best way to stop and re-route traffic across OSPF enabled devices?
A server (SrvA) is connected a router (RtrA) running OSPF (Area 1) connected to a switch (SwA) which is connected via OSPF (Area0) to a different switch (SwB) running OSPF (Area 2) to a router (RtrB) which is connected to a server (SrvB)
Yes, that is correct. Just to ensure my understanding, would this work if it would only be a temporary thing? This (PBR) would be used for a brief period of time then reverted so traffic would be routed normally (within same subnet).
