Re-routing Traffic

[averill.johnson1]

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)

SrvA = 192.168.10.100/24

SrvB = 192.168.20.100/24

SwA = 192.168.10.1/24 (Area1) | 192.168.1.1/30 (Area0)

SwB = 192.168.20.1/24 (Area2) | 192.168.1.2/30 (Area0)

RtrA = 192.168.10.50/24

RtrB = 192.168.20.50/24

(Other pc's on each subnet connected to respective switch.)

A pc with the ip address of 192.168.10.189 destined for 192.168.10.100 (SrvA) needs to be re-routed and sent to 192.168.20.100 (SrvB) with the least amount of interaction.

If it helps switches are 3650's (16.3) and routers are 2901's (15.3).

Hi

You can use PBR to manipulate the traffic. Please correct me but you want to re-route the traffic originated by a PC to a server but using other path, is that correct?

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).
