Description Executing undo ip relay address without ip-address will delete all the relay IP
addresses configured on the current interface.

packets, the interfaces configured with relay IP addresses must support broadcast. In
other words, this command can be used on the broadcast-supported network
interfaces, Ethernet interfaces for example.
