GRE over IPSec ASA

foxdeniss
Level 1
Level 1

Hello.

I want to create a vpn reservation system between offices.

LAN1 - ROUTER1 - ASA1 = (ISP1,2) = ASA2 - ROUTER2 - LAN2

I have 2 ASA with 2 ISP on each, and I have 2 routers on each branch with base license.

I create 2 VPN tunnels between ASAs and 2 GRE tunnels on routers  and EIGRP.

As result:

If I manualy create VPN and after I create GRE all is ok. If channel falls, VPN tunnel is ok, but GRE not work.

If I enter on both ASAs: clear conn address x.x.x.x, then GRE tunnels get up.

As I understand, GRE tunnel creates before IPSEC.

Please help, how GRE can get up automaticaly?

Denis,

Do you need to issue the "clear conn" command in order to bring up the GRE2 tunnel?

Thanks.

Yes, after "clear conn" , GRE2 gets up.

Your thread that's more than five years old solved a problem i have been trying to resolve for a week. I hope you found a solution to the original problem.
