| | Refer to the exhibit. Branch A has a Cisco router. Branch B has a |
| | non-Cisco router set for IETF encapsulation. After the commands |
| | shown are entered, R2 and R3 fail to establish the PVC. The R2 |
| | LMI is Cisco, and the R3 LMI is ANSI. The LMI is successfully |
| | established at both locations. What is the likely problem? |
| | |
| | LMI types must match on each end of a PVC. |
| 19 | |
| | The PVCs at R2 use different encapsulation types. A single port |
| | can only support one encapsulation type. |
| | |
| | Multipoint topologies are Cisco proprietary. The PVC to R3 must |
| | be point to point. |
| | |
| | The ietf parameter is missing from the frame-relay map ip |
| | 10.10.10.3 203 command. |
