Note that, if a common interface module on slot 4 and all the eight label ranges 
corresponding to the rule are not assigned, you must configure the following 
command to prevent the flow in other label ranges not matched from being 
reported to the CPU:

# Configure an ACL redirection rule for denying the MPLS packets with VPLS 
labels.

Symptom 1: PW is not in UP state.

Solution:

■

The LSP tunnel over the public network is not set up for the two ends: verify 
that the route is available on both ends, you can successfully ping the loopback 
port of the peer, and the LDP session is normal.
