Scenario:

Two Vigor3300V routers are to be configured to provide VPN load balancing

VPN Router 1

LAN:192.168.1.1/255.255.255.0

WAN1:192.168.10.11/255.255.255.0 GW 192.168.10.1

WAN2:192.168.20.11/255.255.255.0 GW 192.168.20.1

VPN Router 2

LAN:192.168.201.1/255.255.255.0

WAN1:192.168.30.12/255.255.255.0 GW 192.168.30.1

WAN2:192.168.40.12/255.255.255.0 GW 192.168.40.1

 

Step 1:

Set up a GRE over IPSec tunnel from WAN1 of VPN Router 1 to WAN1 of VPN Router 2.

1.1  Configure GRE over IPSec tunnel in VPN Router 1 for WAN1

1.2 Configure GRE over IPSec tunnel in VPN Router 2 for WAN1

Step 2:

Set a GRE over IPSec tunnel from WAN2 of VPN Router 1 to WAN2 of VPN Router

2.1 Configure GRE over IPSec tunnel in VPN Router 1 for WAN2

2.2 Configure GRE over IPSec  tunnel in VPN Router 2 for WAN2

Step3:

Set a VPN Trunk Group include 2 tunnels set above in VPN Router 1.

Step4:

Set a VPN Trunk Group include 2 tunnels set above in VPN Router 2.
