I am trying to setup two different GRE multipoint tunnels. Tu0 is a regular GRE Multipoint with no IPSEC profile. Works like a charm. Now, I created another tunnel, Tu1 with the same configuration, except I changed the subnet of Tu1 to something different, changed the network-id, and also added an IPSEC profile (tunnel protection). As soon as I turn on Tu1, it kills all of the traffic terminating on Tu0 and I see errors about 'received unencrypted packet' and stuff. It's almost like the traffic starts heading towards Tu1 when it's on. Any ideas? Config is below if it helps. Thanks for any help.
