Example for Configuring VLL-based Ethernet CFM Through Sub-interfaces for
QinQ VLAN Tag Termination
A PE receives a frame with two tags and then accesses a VLL network. To improve reliability
of the network, a sub-interface for QinQ VLAN tag termination is configured on the AC interface
of each PE and is bound to an L2VC interface to access the VLL network. Then, CFM is enabled
on the sub-interface.
Networking Requirements
As shown in
on each switch so that the switch can add Tag 100 to the frames sent by the CE. In this manner,
the IDs of VLANs on the public network are saved. Then, the switch sends user frames with
