Application Examples
Bonding two EoIP tunnels
Assume you need to configure the AT-WR4500 router for the following network setup, where you have
two offices with 2 ISP for each. You want combine links for getting double speed and provide failover:
[Office1] [Office2]
Internet ISP2
Local Net
Local net
10.0.0.1
Eoip-tunnel 1
Eoip-tunnel 2
Internet ISP1
bonding1
Figure 21: Bonding two EoIP tunnels
We are assuming that connections to Internet through two ISP are configured for both routers.
