IPSec VPN using loopback addresses

Unanswered Question
Jan 28th, 2008

Hi all,

I'm trying to set up (what I thought to be) a simple IPSec VPN connection between two routers using the loopback addresses as endpoints but I am having big problems implementing it. The tunnel goes from R1 to R3 through R2 and the IGP used is EIGRP. I've attached the configuration files for both routers.

When I try to do an extended ping from F0/0 on R1 to F0/0 on R3, it fails. With a "debug ip packets" on R3 I see that the source of the IP packets received is 100.1.1.1 (Se1/0 on R1).

What am I missing here to make all this work?

Thank you so much

Eduardo

Case closed.

Right after I posted the question I found a mistake on the config:

"crypto map mymap local-address Loopback0"

should be

"crypto map myvpn local-address Loopback0"

Sorry for the bad post...
