Bay Networks Baystream 7 Configuration And Troubleshooting Manual page 111

The adjacent host entry is required because Bay Networks routers do not
configure a MAC layer address (in this case, a frame relay DLCI entry) as the
destination address of an IP static route entry. In essence, the adjacent host
mechanism provides a workaround solution.
By definition, an adjacent host is a device that is adjacent to yours on the same
network. In the following example, the gateway router is not on the same IP
network. To get to the gateway, a DLCI of 200 maps a PVC back to that router.
You create a pseudo-node in the adjacent host address field, which is a placeholder
to map the pseudo (made up) address of 10.200.0.100 to the known DLCI 200,
rather than to the real address of the gateway router. Then, when the static route
entries to the gateway router destination network of 11.3.0.0 are entered, you can
use the pseudo address 10.200.0.100 as the next hop address. The adjacent host
entry will come into play and tell the CPE router to get to that network it must
send the traffic out DLCI 200.
For a Bay Networks router, the complete static route is a concatenation of the
following:
Static Route
(Destination)
3.1.1.0
For a Cisco router, the complete static route is a concatenation of the following:
Network
(Destination)
3.1.1.0
The following sections summarize how to use Site Manager to configure an
adjacent host and a static route. Refer to Configuring IP Services and to the frame
relay documentation for the CPE platform for a full description of the
configuration parameters and their values.
