Adjacent Hosts

An adjacent host is a network device that is local to a directly connected network.

This device may or may not be a router. For example, Host ID 4 in Figure 1-3 is an

adjacent host to Router Host ID 1. Host ID 6 is not an adjacent host because it is

not connected logically to a directly adjacent network.

The Bay Networks router running XNS software allows you to specify static

transmission paths to adjacent hosts. A static transmission path to an adjacent host

establishes the data link connection necessary for packet transmission along a

static route in a Frame Relay or SMDS network when RIP is not enabled. For

example, in Figure 1-3

the XNS interface on Router Host ID 1 has Host 4

configured as a statically adjacent host. This provides a data link connection that

allows the static routing to occur between Host ID 1 and Network 5.

With adjacent host support, you can do the following:

• Configure the router to map XNS addresses of network devices that are local

to adjacent WANs to their associated WAN addresses

• Configure many static routes that use a single adjacent host as their next-hop

node, thereby reducing manual configuration tasks

Note:

You must use the locally significant data link control identifier (DLCI)

parameter to identify a virtual circuit when you configure a static adjacent host

in a Frame Relay or SMDS network. You must enter the DLCI in hexadecimal

format. (Refer to “Configuring Adjacent Host Parameters” in Chapter 4.)
