Testing LAN Neighbors with Standard Ping

Testing using a ping of another device on the LAN can quickly confirm whether the LAN can pass packets and frames. Specifically, a working ping rules out many possible root causes of a problem. For instance, Figure 23-7 shows the ICMP messages that occur if R1 issues the command ping 172.16.1.51, pinging host A, which sits on the same VLAN as R1.

If the ping works, it confirms the following, which rules out some potential issues: The host with address 172.16.1.51 replied. The LAN can pass unicast frames from R1 to host
