AppleTalk Node Numbering

The AppleTalk node address is an eight-bit number. AppleTalk devices will dynamically

ﬁnd a free node address on startup using an extension of the AARP. You do not need to

perform any node address adminstration.

When you are using dialer maps (for dial-on-demand routing) or some multipoint WAN

data links, it is useful to tell the access server what node address to use. This can be done

using an optional ﬁeld on the appletalk cable-range command as follows:

appletalk cable-range 3-4 1.129

AARP is used to resolve network layer node addresses with data link addresses. Enter the

command show apple arp to examine the AARP table.
