i need to ask you regarding GET vpn desgin .i know there is a KS server which used to encryption policies, such as interesting traffic, encryption protocols, security association, rekey timers, and so on, are centrally defined on the KS and are pushed down to all GMs at registration time.
and GM is an IOS router responsible for actual encryption and decryption i.e. a device responsible to handle GET VPN data plane.
i want clearification can one router act as a GM annd KS server both simultaneously .
MY client suppose to upgarde their network i want to shift their network from DMVPN to GETVPN and network based on HUB ad spoke topology
Thanks in advance
