While back, someone told me that ppp multilink and IPSEC does not work well
together,

Can is anyone using ppp multilink and IPSEC together?
And Do you have any problems?

Thanks,

It seems you could still use multilink if you apply the encryption settings
to the Virtual Interface created by the multilink bundle (i.e. Setup and use
a virtual template for your PPP mulilink, and the T1s will be combined into
a single Virtual Interface) This should avoid the mismatched passwords as
there would only be one.

If I do multilink,

Since packet can take either T1 to,
Crypto map password does not match for some packets and will have to
retransmitt. And will not work..

How about combining them into a multilink interface?
