Next, let’s fill in the information for circuit #2 (192.168.2.0 network using .1 and
.2):
Router Diekman Shadow Knight
S0/0 none none none
Adtran 1/1 1/2 2/1
Dlci 16 18 17
S0/0.16 none 192.168.1.2
S0/0.17 192.168.2.1 none
S0/0.18 192.168.1.1 none 192.168.2.2
Finally, let’s fill in the information for circuit #3 (192.168.3.0 network using .1
and .2):
Router Diekman Shadow Knight
S0/0 none none none
Adtran 1/1 1/2 2/1
Dlci 16 18 17
S0/0.16 none 192.168.1.2 192.168.3.2
S0/0.17 192.168.3.1 192.168.2.1 none
S0/0.18 192.168.1.1 none 192.168.2.2
Eh, voila! We are ready to configure our routers. Let’s configure our serial
interface and sub-interfaces on “knight” (dlci #17)
knight(config)#int s0/0
knight(config-if)#enc frame-relay
knight(config-if)#frame-relay lmi-type ansi
knight(config-if)#no shut
knight(config-if)#int s0/0.16 point-to-point
knight(config-if)#ip address 192.168.3.2 255.255.255.0
knight(config-if)#no shut
knight(config-if)#frame-relay interface-dlci 16
knight(config-if)#int s0/0.18 point-to-point
knight(config-if)#ip address 192.168.2.2 255.255.255.0
knight(config-if)#no shut
knight(config-if)#frame-relay interface-dlci 18
do not forget to use your “cut and paste” utilities…these are a time-saver!
The last line (frame-relay interface-dlci 18) just identifies the dlci connection
(in this case to our Adtran). Now isn’t that nice that we already have it in our
drawing. Notice how there is no ip address on S0/0. A good way to doublecheck
yourself: Knight connects using dlci #17 so we should have sub-
