NOTE
In inter-AS VPLS Option A, for the same VPLS network, the VPN target of the VSI on the ASBR and that
on the PE in the same AS must be matched. The VPN target of the VSI on the ASBR and that on the PE
in different ASs need not be matched.
7.7.3 Checking the Configuration
In inter-AS Kompella VPLS OptionC, devices in the SP network only need to establish outer
tunnels on PEs of different ASs. ASBRs do not need to maintain information about the inter-
AS L2VPN or reserve sub-interfaces for the inter-AS L2VPN. Actually, L2VPN information is
exchanged only between PEs. As a result, this solution requires fewer resources and less
configuration workload.
Prerequisite
The configurations of the Inter-AS Kompella VPLS function are complete.
Procedure
l
Run the
display bgp vpls
group
[
group-name
] command to check information about BGP
VPLS peer groups on the PE or the ASBR.
l
Run the
display bgp vpls
peer
[
ipv4-address
verbose
] command to check information
about BGP VPLS peers on the PE or the ASBR.
l
Run the
display bgp vpls
all
command to check information about BGP VPLS label blocks
on the PE or the ASBR.
l
Run the
display vpls connection
[

to check the VPLS connection on the PE.
l
Run the
display bgp routing-table label
command to check label information about
labeled IPv4 routes on the PE or the ASBR.
l

*
command to check the PEs and P that packets pass
from the sender to the receiver on the VPLS network and check the connectivity of Layer
2 links, which helps to locate the faulty node on the network.
In OptionA mode, the ping and trace functions support intra-AS detection.

Example
After the configurations, run the
display bgp vpls
peer
command on the PE or the ASBR. You
can view that the status of the BGP VPLS peer between the PE and the ASBR in the same AS
is "Established". For example:
<Quidway>
display bgp vpls peer
BGP local router ID : 1.1.1.1
Local AS number : 100
Total number of peers : 1 Peers in established state : 1
