R3102-R3103-HP 6600/HSR6600 Routers MPLS Configuration Guide

217
Step Command Remarks
5. Specify the multicast
suppression ratio for the VPLS
instance.
multicast-restrain ratio
Optional.
100 percent by default.
6. Specify the unknown unicast
suppression ratio for the VPLS
instance.
unknown-unicast-restrain ratio
Optional.
100 percent by default.
7. Specify the encapsulation
type of the VPLS instance.
encapsulation { bgp-vpls | ethernet
| vlan }
Optional.
vlan by default, which
corresponds to the VSI PW
encapsulation type of tagged.
8. Set the MTU of the VPLS
instance.
mtu mtu
Optional.
1500 bytes by default.
9. Set the description of the VPLS
instance.
description text
Optional.
No description set by default.
10. Shut down the VPLS service of
the VPLS instance.
shutdown
Optional.
By default, the VPLS service of a
VPLS instance is enabled.
11. 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,
GRE tunnel, CR-LSP tunnel.
For information about configuring
a tunneling policy, see
"Configuring MPLS L3VPN."
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:
Task Command Remarks
Use MPLS LSP ping to test the
connectivity of a PW.
ping lsp [ -a source-ip | -c count |
-exp exp-value | -h ttl-value | -m
wait-time | -r reply-mode | -s
packet-size | -t time-out | -v ] * pw
ip-address pw-id pw-id
Available in any view.
MPLS LSP ping can be used to
inspect only an LDP PW.
