We are using site to site VPN between Cisco 3700 Routers. the sites has GRE tunnels and it is encrypted using IPSEC, the IKE authentication method is pre-shared keys
We are looking for VMS to allow us to manage the pre-shared keys (for example allow us to change all the keys on all our Routers quarterly without the need to log on each router and issue CLI commands).
My question is:
Did anyone implemented VMS for this purpose before, can it manage the keys in the way described above?
Appreciate your help
