Why Cannot an IPSec Tunnel Be Established Until It Is Restarted?

Why Cannot an IPSec Tunnel Be Established Until It Is Restarted?

When the same traffic needs to be sent to the headquarters but an IPSec tunnel exists between the branch and headquarters to protect access traffic from existing users, a new IPSec tunnel cannot be established before the old IPSec tunnel is torn down after it is restarted on the headquarters device.

To solve the problem, run the ipsec remote traffic-identical accept command to enable new users with the same IPSec rule to quickly access the headquarters. This function quickly ages an existing IPSec SA between the branch and headquarters to re-establish a new IPSec tunnel.
