Fabric Extend over E-LAN/VPLS (L2) network using
VLAN Tunnels
Fabric Extend can also be transported over a layer 2 core without using VXLAN IP tunneling. In this case,
logical ISIS interfaces are tunneling using B-VID translation where the two B-VLAN ID’s are mapped to two
different logical VLAN ID’s. Please note that two core VLAN ID’s are required for each point-to-point NNI
connection between two BEB nodes. In in case, the ONA is not required with the VSP 4000, however, the
third party core network must support jumbo frames.
