IPSEC Site to Site VPN Encryption domain update

[JASPAL_SINGH]

Hi All,

I have updated the Encryption domain for exiting Site to Site IPSEC VPN. Tunnel is up and active.

Communication is not ok to the IP that is added recently. Policy is installed.

In zdebug error is coming like " encryption failed".

I doubt we need to reset the tunnel but I did not reset the tunnel yet.

My query is like do we need to reset the tunnel after we update the existing encryption domain ?

Thank & Regards,

Jaspal Singh
