The new interface is point-to-point, and the destination address type, addrtype, can either be dstaddr or broadaddr. The address type is determined by the interface definition in the NCP generation. The destination address may be coded such that the network or subnetwork directed broadcast address is used or that the unicast or host address representing the other end of the point-to-point link is used. This address is used for sending routing information over an interface to the destination router or host. The exception is when the interface is multicast-capable; the multicast address is used.
