Configuring IP routing with a Frame Relay Link 145
Access Server Administrators’ Reference Guide 13 • Frame Relay
• active(2)—The link is up and passing data. This is the desired condition of the link.
• invalid(3)—The link is down and not passing data. Reasons for this may be your service provider hasn’t
enabled your service or the link is not yet connected to your access server.
• needIPaddr(4)—This is when the IP address needs to be entered for this DLCI..
• wait4peer(5)—In this state, the Link is waiting for the far end to synchronize.
Committed Burst (bits) (frCircuitCommitedBurst)
This specifies the committed data rate for the link in bits-per-second.
Excess Burst (bits) (frCircuitExcessBurst)
This specifies the excess data rate for the link in bits-per-second.
Throughput (bits) (frCircuitThroughput)
This specifies the throughput for the link in bits-per-second.
IP Address (FrameIPAddr)
As all of the interfaces on the access server run in un-numbered mode, the IP address to enter is that of the far
end router. This is not the IP address of the access server. After the IP address is entered, it will appear as a
point-to-point link in the IP routing table with this address.
Congestion (frameEnableCongestion)
This option enables or disables congestion tracking.
• enable(0)—Enables Congestion tracking
• disable(1)—Disables Congestion tracking
Adding DLCIs
To add DLCIs, type the following information under the
Add DLCIs
section:
1. Under the
DLCI
entry, type the number given to you by your provider.
2. Under the
IP Address
entry, type the IP address of the far-end router. That would be the next-hop router
for this DLCI. Often, this will be the Ethernet address or loopback address for that router.
3. Click on
Submit Query
.
Configuring IP routing with a Frame Relay Link
As each properly configured DLCI will have an IP address representing the next hop on that link, the access
server can use a Frame Relay link to access many remote networks. The IP address of the Frame Relay link is
unnumbered and specifies the next hop to another router. As such, it is a single-host route with a mask of
255.255.255.255. By using the access server’s routing table, you can apply any number of network routes to
use the Frame Relay link. You can even use a PVC as the default gateway (0.0.0.0).
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).
