Hello all,
Ok, draw this out if you can as it is not that complex. I have a hub (Chicago) site and a spoke (Los Angeles) site. Chicago consists of a VPN 3020 Concentrator, a 7204, and a 3560 Layer2/3 switch. LA has a 2610 2820, and a PIX 501 on one network all plugged into one switch. There is a tunnel established over a DSL line between the PIX and the 3020 used as a backup line for the primary line which is a MPLS network. The MPLS network is connected from the LA to Chicago via the 2820 and 7204 and inbetween those are of course the MPLS cloud. LA's default gateway for PC's is the 2610 router. Chicago's gateway is the 3560. EIGRP is running between the 2620, 7204, and 3560. Since the PIX and 3020 cannot run EIGRP, I am trying to get the networks between Chicago and LA to dynamically failover if the MPLS line goes down. I was told I can use a GRE tunnel over the IPSEC VPN tunnel and route EIGRP through that so if the primary goes down, the 2610 in LAX knows to dynamically send the traffic out the PIX.
Since then I have tried to create a GRE tunnel and I can get it up and the tunnel keeps flapping up and down. I was told to use loopback interfaces but have not tried that. Before I get more into deatil with IP configs, can someone help me? Thanks,
Jimmy K
