  FEC 129-based Pseudowire Service Discovery
Viewing FEC 129 Type I-based Pseudowire Tunnel from VPLS Map view
The FEC 129 Type I pseudowires are associated to VFIs, which in turn are associated to PBB bridges 
(that is VFIs are attached to B-bridges, and B-bridges are attached to I-bridges on both the FEC 129 Type 
I pseudowire peers). 
The following services help in viewing the components involved in forming the FEC...

Step 3For both the peers, select the PBB bridges associated to the VFIs. The bridges can be filtered using the 
name of the bridges.
NoteI-SID can also be used for filtering I-bridges. 
Step 4On adding the PBB-bridges to the map: 
A link is formed between the associated VPLS plugin and the B-bridges for both the peers.
A link is formed between the I-bridges and the B-bridges...

If the above topology has PBB bridges configured on either ends, then the following are displayed in 
addition to the above components and links:
Association between the I-bridges and the B- bridges (of both the FEC 129 Type I pseudowire 
peers).
Association between the B-bridges and the VPLS instances. For further viewing the components
