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.
