2.1.4.3 - Unnumbered Links
An unnumbered link does not use network addressing on the WAN link. The WAN
connection is roughly equivalent to an internal connection with each of the two end point
routers operating as half of a complete router that is connected between the two endpoint
LANs.
When an IPCP link is set to unnumbered, the only configuration option applicable is Peer
IP Address. The peer IP address in this case is the IP address of the remote PPP router,
that is the IP address of its LAN connection. If the peer IP address is not specified, the
IOLINK router will attempt to determine it when negotiating the IPCP connection.
When an IPXCP link is set to unnumbered, no addressing configuration is required. All of
the IPX settings are negotiated during the IPXCP connection.
When making a raw frame relay (no PPP encapsulation) connection with
unnumbered links, the IP network address of each partner router must be manually
entered in the remote site set-up for the link to operate.
