  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 129 Type I-based 
pseudowire topology:
VPLS view—You can view the FEC 129 Type I pseudowires that are attached to the VFIs from the 
VPLS view. These VFIs are in turn attached to the PBB bridges. To view the VFIs, refer Vi ew i n g  
VPLS, page 17-85.
Bridge Domain view—From the bridge domains service, you can view the PBB bridges (I-bridges 
linked to the B-bridges). To view the bridge domains, refer Viewing Bridge domains, page 17-85.
NoteIn addition to PBB bridges, regular bridges, with no associations to pseudowires or VFIs, can 
also be discovered in the Bridge Domain service.
Viewing VPLS
To  v i e w  t h e  V F I s :
Step 1Choose Add to Map > VPLS to open the Add VPLS Instance to map dialog box.
Step 2In the Add VPLS Instance to map dialog box, select Show All to display the list of VPLS instances.
Step 3Add the required VPLS instance from the VPLS list. It can be filtered either using the VPN-id or the 
names of the associated VFIs. 
Step 4Once the VPLS instance is added to the map, it displays the link between the two associated VFIs. On 
further expanding these VFI components, you can view the associated FEC 129 Type 1 pseudowire 
peers, linked to these VFIs on either ends. 
Step 5Click the link between the two associated FEC 129 Type 1 pseudowire peers to display the topology link 
properties window. This link is specific to these FEC 129 Type 1 pseudowire peers. 
Unlike the Map view, topology properties which display all the topology links between the two VNEs 
are added to the map. Refer Viewing FEC 129 links from Topology View, page 17-80.
Viewing Bridge domains
To view the bridge domains associated to the VFIs, follow the steps provided below:
Step 1Open the Add Bridge Domain dialog box in one of the following ways:
Choose File Add to Map > Bridge Domain.
In the toolbar, click Add to Map and choose Bridge Domain.
NoteThe Bridge Domains must be added to the map containing the VPLS instances to view the 
associations between them.
Step 2In the Add Bridge Domain dialog box, select Show All to display the list of bridge domains.

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 for both the peers.
Viewing FEC 129 Type I-based Pseudowire Tunnels from Virtual Connection 
Map View 
The Virtual Connection view displays the logical association between the FEC 129 type I pseudowire 
peers in a single view.
To view the end-to-end connection between the FEC 129 type I pseudowire peers:
Step 1Open the Add Virtual Connection to Specific plugin dialog box in either of the following ways:
In the toolbar, choose Add to Map > Virtual Connection. 
In the menu bar, choose File > Add to Map > Virtual Connection. 
Step 2In the Add Virtual Connection to Specific plugins dialog box, select the FEC 129 type I-based 
pseudowire virtual connection that you want to view.
Step 3To view a specific FEC type I pseudowire, filter using the I-SID, VPN-id, or the names of the associated 
VFIs to identify the FEC Type I pseudowire.
Step 4Click OK to add the selected virtual connection component to the map. 
Step 5You can view the following FEC 129 Type I pseudowire information for the selected virtual connection 
component added to the map:

Viewing FEC 129 Type I Pseudowire Properties from Virtual Connection View, page 17-87
Viewing FEC 129 Type I Pseudowire Links from Virtual Connection View
To view the end-to-end connection between the FEC 129 Type I-based pseudowire peers:
Step 1Click the Expand (+) icon to view the associated components and the links:
Association between the VPLS instances. Click the Expand (+) icon on the VPLS instances.
Association between the VFIs, which on further expansion, displays the corresponding components.
Association between the FEC-129 Type I-based pseudowire peers. To view the topology Link 
Properties window, click the link between the two associated FEC 129 Type I-based pseudowire 
peers.

  FEC 129-based Pseudowire Service Discovery
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 
attached to the VPLS instances, navigate to Step 1.
Viewing FEC 129 Type I Pseudowire Properties from Virtual Connection View
To view the virtual connection properties of FEC 129 type I pseudowire peers:
Step 1Right-click the selected virtual connection component in the map.
Step 2Click the Properties tab to display the EVC hyperlink.
Step 3Click the EVC hyperlink to view the EVC terminating points.
