Configuring dynamic vpn tunnels, however this small network is using frame-relay with sub-interfaces. On the hub router, when configuring the tunnel source you can only enter a single interface, if I have 2 remotes, I have 2 sub interfaces, how do you accomdate multiple remote sites when you are using more than one wan interface ??? Online documentation states use a SINGLE tunnel interface, and this cannot deviate as you must use a single subnet for the NHRP network ??
