1. Source to Destination routing.  all traffic going via OLD Network. Only trying to change Vlan-3 Network should route Via New Network.

2. No static route need to add on Nexus.

3. Nexus Vlan-3Interface  IP will not participate in PBR , because PBR has limitation in feature. but the other IP in Vlan-3 will route to New Network Link.

5. Firewall has only static routes.
