Hub-Spoke DVPN configuration example
Network requirements
In the Hub-Spoke network shown in Figure 329 , data is forwarded along Hub-Spoke tunnels. The main
and backup VAM servers manage and maintain information about the nodes. The RADIUS server (a
CAMS or IMC server) performs VAM client authentication and accounting. With each being the backup
of the other, the two Hubs perform data forwarding and routing information exchange.
Establish a permanent tunnel between each Hub-Spoke pair.
