Hello all,
We recently purchased DrayTek Vigor 2600X routers to replace our frame-relay circuits with VPN tunnels between sites. We were going to have the VPN tunnels running alongside the frame-relay until all issues were worked out and we were confident that it would be reliable. We have 2 routers configured but when the VPN tunnel is established between them, the frame-relay circuit to the 3rd site is clogged with traffic and brought down (it is only a 32kbps link). Using a packet sniffer it looks as though the extra traffic is broadcast traffic from the remote site through the VPN tunnel.
Does anybody know if the router picks up all broadcast traffic (to IP 255.255.255.255) and sends it through the VPN tunnels and then if the router at the other end does the same? It looks as though we are getting into some sort of loop because the traffic is persistant and the network flooded whenever the tunnel is up and both routers plugged into the LAN.
Any help/advice would be appreciated!
