5.9 Connecting Sub-interfaces to a VLL Network

This section describes how to connect sub-interfaces of a PE to a VLL network so that CEs can
communicate with each other.

5.9.1 Establishing the Configuration Task

Applicable Environment
A CE accesses the ISP network through PEs. The user data packets sent from the CE to a PE
contain one or two tags. You need to connect the sub-interfaces on the PEs to a VLL network
to enable CEs to communicate with each other.
Pre-configuration Tasks
Before connecting sub-interfaces to a VLL network, complete the following tasks:
