VPN not coming up between Nortel contivity and Cisco ASA 5520


One of my vendors has a cisco ASA5520 and we are trying to build a VPN tunnel between ASA 5520 and Nortel 4500 contivity box.

It passes phase 1 and during phase 2 i get this error message


3|Dec 06 2006|11:51:39|713119|||Group = IP = 1 COMPLETED

Similarly when we check at the remote Contivity box, we get the similar error and it says as


11/16/2006 12:43:39 0 Branch Office [01] IPSEC branch office connection initiated to rem[]@[] loc[]

11/16/2006 12:43:39 0 Security [11] Session: IPSEC[] attempting login

Invalid ID info generally means when the networks are not matching else when we use different routing where one end is static or other end is dynamic. But in tihs case we check that as well and still we get the same error.

any clue how to troubleshoot further.

Re: VPN not coming up between Nortel contivity and Cisco ASA 552

I fixed this issue myself after changing the IKE parameters in Cisco ASA box

"isakmp identity automatic" from

"isakmp identity address" in the global settings.

every thing started working fine now
