Hi and thanks for the explanation. When I use CA for rsa-sig authentication, do the routers contact CA and download certificates each time they build IPSec tunnel or it happens just once during the router preparation for rsa-sig?
Many thanks for your help.
PS. I am trying to build s2s IPSec tunnel between 2 peers but authenticating as hostnames (dynamic IPs). Pre-share doesn't work even with crypto isakmp identity hostname.
