GRE over IPSec - Two ISP's

[Shobith K]

Hi,

I have a 2851 Router VPN bundle with 2 ISP's terminating on it. Both the ISP's are load balanced by a LoopBack IP configured on the router and the appropriate routes adding to it. I wanted to have one GRE over IPsec tunnel to one of our client places. We have configured that also, but that is not working. We have applied the crypto map on loopback interface, there is some confusion in it. can anyone help me in this.

Shobith,

Why have you applied crypto map to loopback interface? Paste your configs at either ends for further troubleshooting.

first be sure that the GRE tunnel works properly

then you must apply crypto map on the tunnel.If this isn't helpful, please give us more details, like the configuration itself

Best Regards
