IPv4 multi-hub-group ADVPN configuration example
Network requirements
As shown in Figure 152, the primary and secondary VAM servers manage and maintain VAM client
information for all hubs and spokes. The AAA server performs authentication and accounting for
VAM clients.
• Configure three hub groups to accommodate all ADVPN nodes:
{ Hub group 0 contains Hub 1, Hub 2, and Hub 3.
{ Hub group 1 contains Hub 1, Hub 2, Spoke 1, and Spoke 2. Hub 1 and Hub 2 back up each
other.
{ Hub group 2 contains Hub 3, Spoke 3, and Spoke 4. Hub groups 1 and 2 use full-mesh
networking.
• Allow any two spokes to establish a direct spoke-spoke tunnel.
