However, if the connection is off-line, Router A will use Member 2 VPN tunnel (with L2TP
over IPSec) instead to connect Router B right away.
Example 2: Subsidiary in Asia can use vigor router as VPN client. Every day it should
transmit ERP, Mail or order information to headquarter in Europe. The Vigor router can
build another backup VPN tunnel to subsidiary in America through LAN-to-LAN, and the
VPN server in the subsidiary in American can build Routing /RIP. When the VPN tunnel is
off-line, the subsidiary in Asia can send the data (that should be transmit to headerquarter in
Europe) to the subsidiary in America, then the subsidiary in America transmit the data to
headerquarter in Europe through VPN server by using VPN tunnel backup connection.
