An NBMA address for broadcast or multicast packets
This command defines a nonbroadcast multi-access (NBMA) address to which to send broadcast or multicast traffic. An NBMA address is a MAC address for Ethernet networks or an NSAP address for ATM networks. A configuration may include several of these commands, each defining another NBMA address. This command allows you to send multicast traffic through a tunnel that crosses networks that do not support IP multicasting. It may be used only on tunnel interfaces.
