We have a Cisco router at the HQ and several remote sites with Cisco routers. Remote sites are connected to the direction via local radio loop, no NAT. The routing is static.
We replaced the Cisco router at HQ with a 580 balance, and connected the local radio loop on a LAN port to define static roads. On some remote sites we have replaced the Cisco router with a peplink and added an internet connection to mount a PEPVPN tunnel with the 580 scale.
The problem currently is that when the tunnel is established we have an IP address conflict that means that when the local radio loop is cut, the traffic is not automatically switched into the tunnel. It first removes the static road in the scales 580 so that the tunnel works.
The complete replacement of the Cisco routers of the remote sites is under discussion, the question of the auto rocking must be effective to convince the client.
Is there a way to manage this issue?
