Hello, here's our network diagram and perhaps someone could help me on this.
Currently we have MPLS connection between site A (Cisco 2621XM) and B (Cisco 2621XM) and also have Nokia IP350 firewall (with Checkpoint NG FP3) on each site to establish site-to-site VPN connection.
(Cisco 2621XM) ---------- MPLS Cloud --------- (Cisco 2621XM)
(Nokia IP350) ----------- Internet ----------- (Nokia IP350)
We've been using VPN connection over the internet until we have MPLS T1 terminated. As soon as I enabled the ethernet interface of MPLS router, we lose VPN connection and still not able to talk to any host at the other end. Looks like we have some routing issues. I have to shut down the ethernet interface in order to maintain VPN connection.
Is it possible to keep all the interface enabled and switch MPLS as the primary link and Internet T1 as secondary link?
So that when primary link has a problem, it could fail over to secondary link automatically.
Thank you very much for your help in advance.
