146 Configuring IP routing with a Frame Relay Link
When the Frame Relay link (DLMI) and a DLCI is in the UP state, its IP address and interface, will appear in
the IP Routing table (see figure 43). The IP address of the PVC will not appear in the IP routing table if the
Frame Relay link is down, or the DLCI is not configured or inactive.
Figure 43. IP routing with Frame Relay example
In figure 43, the Frame Relay link shows the address of 192.168.1.3. As IP routing dictates the best fit for any
forwarding decisions, any destination with this address will automatically be sent across the Frame Relay link.
Figure 43 also shows a network route using the Frame Relay link as its next hop. The destination of
192.168.1.0 255.255.255.255 specifies the gateway, or next-hop, of 192.168.1.3. With this entry, any IP
packet with the destination address in the range of 192.168.1.1- 192.168.1.254 will automatically be sent
down the Frame Relay link to the device with the IP address of 192.168.1.3.
Adding a route
To add a route, do the following:
To access the IP routing table in the access server:
1. Click on
IP
under the
Configuration Menu
to to display the
IP
window (see figure 49 on page 161).
2. Click on
Routing Info
(see figure 49 on page 161).
Note To add a network route, use the second set of entry items which allow
for a destination, mask and gateway:
