As discussed in Setting Up Dual-Hop Emulation using more than two links allows you to set different network conditions for a single or group of IP addresses, applications or VLANs. Using our previous examples we now have two locations with four links (2G, 3G, 4G, and No impedance) combining into one WAN link.
This scenario is similar to the previous and would be configured as shown here:
Links 1, 3, 4 and 5 are 2G, 3G, 4G, and No impedance, respectively. Link 2 is configured as the WAN link.
