Finding this list is easy when learning and wanting to remember how to solve a given problem. Candidates do not need to memorize this list and can digest the information with practice to understand it.The correct PVC can be found through sub-steps a, b, c, and d of Step 3. After that, Step 3 of the troubleshooting process explains the status of these PVCs and the interfaces and sub-interfaces associated with them to determine the cause of the problem.This subsection gives an example of R1 not being able to ping through R2 Frame Relay IP address 10.1.2.2 and explains its further analysis. Before focusing on how to determine which VC to use, it is helpful to look at the final answer, and Figure 14-8 lists some of the detailed information. For this example, the current situation is that the ping 10.1.2.2 command for R1 failed.R1 routing tableSubnet egress next hop10.1.2.0/24S0/0/0.2 N/AFigure 14-8 Configuration scenarios associated with the failure of the ping10.1.2.2 command for R1(1 ) Find the connected subnet and output interface (sub-steps a and b of step 3).Finding the first two sub-steps (sub-steps 3a and 3b) of the PVC (DLCI) that R1 connects to R2 is fairly easy if you have already studied Part II and Part III of this book. Any time you ping the frame relay IP address of an adjacent router, that IP address should also belong to a subnet that connects to the local router. In order to find the interface used by the local router to forward packets to the remote router, this common connection subnet must be found.Several commands are shown in Example 14-20 that use R1 ping 10.1.2.2 0 to confirm that R1's S0/0/0.2 subinterface is connected to subnet 10.1.2.0/24, which includes R2's IP address 10.1.2.2.
