multiple VPN's between cisco 2811 and RB450's

Hello people, who can help me with information, how i can connect
multiple RB450’s with Cisco2811 in VPN with encryption.
I can’t find infos.

I try to connect via IPSEC, but it work only with one tunnel.
I try to use the VTI, but after some period, mikrotik loose the link,
it work 2-3minutes…

More detail required. How about posting your IPSEC configuration from each end?

Kind regards

Andrew

hi, have you any solution for connecting rb400 with more than one Cisco 2811 router ?
