IPv6 Connectivity
To test the connectivity of a network, many network devices support the Echo
diagnose and locate the connectivity problems in a network.
T v6 command runs in the user EXEC mode and privileged EXEC
mode. In the user EXEC mode, only basic ping IPv6 functions are available.
H ode, extended ping IPv6 functions are
a
protocol. The protocol sends a special packet to a specified network address
and waits for a response. This allows you to evaluate the connectivity, delay
and reliability of a network. The ping tool provided by DES-7200 can effectively
