Hub-and-Spoke IP Tunnels over L2 segment
Please note the VSP 8000 and VSP 7200 only supports a single next hop IP address. If the core
network is a flat layer 2 network from the main site to multiple spoke sites, a VSP 4000 with ONA
can be used instead of the VSP 8000 as it does not have this restriction. However, a VSP 8000
or VSP 7200 can still be used at the main site by adding a loopback interface to a second VRF
and using this interface as the tunnel source IP address. Please see the configuration example
shown below under the section titled “Fabric Extend over E-LAN/VPLS (L2) network
using Layer 3 over Layer 2 tunneling with VSP8000 or VSP7200”.
