Configuring a WAN Routing Service
Page 29-60

Step 2. Set Up a Frame Relay Routing Service

You create a Frame Relay routing service using the cas command. Follow the steps below to
set up a routing service.
1. Enter the cas command followed the slot number, a slash (/), the port number, and then
the service number for the routing service:
cas 2/3 1
A screen similar to the following displays:
Slot 1 Port 2 Service 3 Configuration
1) Description ................................................................... = Frame-Relay
{Enter up to 30 characters}
2) Service Type ................................................................. = Bridging
{(T)runking, (R)outing, (B)ridging}
3) Administrative Status .................................................... = Enabled
{(E)nable, (D)isable}
4) VC(s)............................................................................. = 0
5) VLAN Group(s).............................................................. = 0
6) Frame-Relay Bridging Mode (Applies to Bridging Only).. = Bridge All
{Bridge (a)ll, (E)thernet only}
(save/quit/cancel)
:
You make changes to the options in this screen at the colon prompt (:). You make
changes by entering the line number for the option you want to change, an equal sign
(=), and then the value for the new parameter.
2. Enter a description of this routing service by entering 1, an equal sign (=), and then a
description for this service. Your description can be up to 30 characters long.
1=<router service name>
When you are done entering a description, press <Enter>.
3. Specify that this is a routing service by entering a 2, an equal sign, and an R as follows:
2=5
This specifies that you want to set up a routing service, as opposed to a Trunking or
Bridging service. Press <Enter>.
4. By default, the routing service is Enabled. This means that as soon as you are done
configuring the service, it will begin routing Frame Relay traffic. If you would like to
disable this routing service now and enable it later, enter 3=D and press <Enter>.
5. You need to specify the DLCIs of the virtual circuits to include in this routing service.
Multiple VCs may be configured for a single routing service and all configured VCs will
map to a single virtual router port. Enter a 4, an equal sign (=), and then the DLCI
numbers for each virtual circuit. Separate DLCIs with spaces, as shown in the example
below.
4=16 17
Press <Enter> after you enter all virtual circuit DLCIs.
