Specify a tunneling policy for
the VPLS instance.
tnl-policy
tunnel-policy-name
Optional.
By default, no tunneling policy is
specified for a VPLS instance and
a VPLS instance uses the default
tunneling policy. The default
tunneling policy selects only one
tunnel in this order: LSP tunnel,
CR-LSP tunnel.
For information about how to
configure a tunneling policy, see

Inspecting PWs
On a VPLS network, you can use the MPLS LSP ping function to test PW connectivity and get necessary
information for troubleshooting PW failures.
On the local PE, the MPLS LSP ping function adds the label of the PW to be tested into MPLS Echo Request
messages so that the messages travel along the PW. The local PE determines whether the PW is valid and
reachable according to the replies received from the peer PE.
To test the connectivity of a PW:
