MLPP and ipsec VPN's.

I think this is something that should be able to be done, but I want to verify it before we make the final cutover. I have several ipsec vpns going from my router to other routers/firewalls on the internet. This was/is fine going out a single interface, but we are moving to a dual T1 setup using multilink. I have had a heck of a time even find example configurations for MLPP on a 3600 let alone an example of a VPN one. Any information would be appreciated.

Re: MLPP and ipsec VPN's.

I have setup MLP on 2600 and 3620 router with VPNs. Getting to to work is very dependant on the version of the IOS you are running. The first version of the IOS that I got it to work with (consistently)was 12.1(5)T7. If you are using the AIM-VPN module then :-(.

All you need to do is create an new MultiLink group and put the serial ports in the group.
