If a static map is used. the broadcast keyword is required to support the routing protocol.For a complete demonstration of the above, Example 14-23 shows the output of the show frame-relay map command on router R1 shown in Figure 14-7, where there is no problem mapping (the previous problem has been fixed). In this example, interface S0/0/0.2 is a point-to-point subinterface, and14.2 Base Content 309 S0/0/0.34 is a multipoint subinterface, and one is mapped with reverse ARP learning and one with static configuration. Example 14-23 The showframe-relay map Command on R16. End-to-End Encapsulation (Step 5)End-to-end encapsulation on a PVC refers to the header that follows the Frame Relay header and is available in two options: a Cisco-specific header and an IETF standard header. The details of its configuration are described in the "Encapsulation and LMI Configuration" section of this chapter.It turns out that mismatched encapsulation settings on the router at the opposite end of the link can lead to problems in one particular case. If one router is a Cisco router with Cisco encapsulation and the other router is a non-Cisco router with IETF encapsulation, a mismatch in encapsulation types can cause ping failures. However, two Cisco routers can understand both encapsulation types, so the above problem does not arise in a Cisco-only network.7. Mismatched Subnet Numbers (Step 6)At this point, if the problems identified in the first 5 steps of Troubleshooting 6 have been resolved, then all Frame Relay problems should have been resolved. However, if the routers at each end of the PVC have misconfigured IP addresses in different subnets, the router will not be able to ping through to the other router, and the routing protocol will not be able to become contiguous. Therefore, the final step should be to confirm the IP addresses and subnet masks on each router and make sure they are connected to the same subnet. This can be done by simply using the show ip interface brief and show interfaces commands on both routers.14.3 Preparing for the Exam14.3.1 Reviewing the Exam Essentials
