i have a problem in the VPN connection between the a cisco router 2600 and a Nortel router.
during the test, i issued the "sh crypto isakm sa" command and get the connection state of MM_NO_STATE. i think that this is a phase 1 connection problem.
taking into consideration that all the VPN phase 1 prameters are matched between the two devices (encr, auth, hash, life time).
is there a compatibility between the cisco and Nortel for VPN connection, or not.
i attached a part of cisco router conf file.
