| 1: | What is the innermost label in the label stack of a packet sent over an AToM pseudowire? |
| 2: | How do the peer PE routers discover each other? |
| 3: | How do the peer PE routers advertise VC labels to each other? |
| 4: | If an attachment circuit changes state to down, how does the PE router indicate this state change to its peer PE router? |
| 5: | How do LDP LSRs with directly connected interfaces discover each other? |
| 6: | How do LSRs with directly connected interfaces establish an LDP session? |
| 7: | Assuming that the PE routers are not in a back-to-back configuration (or directly connected via a GRE or L2TP tunnel), what is the minimum number of labels required to transport Layer 2 PDUs across an MPLS network between ingress and egress PE routers? |
| 8: | How many LSPs are required to establish a single AToM pseudowire between peer PE routers? |
| 9: | What is a likely cause if labels are not locally assigned to prefixes? |
| 10: | Assuming an LDP signaled tunnel LSP, to what prefix does the tunnel (IGP) label correspond? |
