Cisco IPSec lan to lan tunnel - encryption domain.
Imagine you have two sites connected by an IPSec tunnel. Site A can send traffic from 10.10.10.10 to 192.168.10.10 at site B. Each side is using a Cisco ASA firewall. Now one day you want to add 192.168.10.11 as a destination. If you added that to site B's firewall without also updating site A's firewall with like information - would the tunnel then break? Thank you.
The issue is I have a tunnel I need to change and several companies to communicate with on the far end. It would be ideal if I could update my end of the tunnel and let them update their side when they get to it. But if I recall correctly I think if I add another host to the encryption domain at site B the tunnel will just fail. Any insight?
