LAB 18 – ISDN BRI-BRI config
Router IP Address Mask SPID1 Local Tel# ISDN Switch
router1 200.10.1.1 /24 32177820010100 7782001 basic-ni
router2 200.10.1.2 /24 32177820020100 7782002 basic-ni
ISDN Parameters
1. In this lab, you will configure ISDN BRI on router1 and router2 using dialer profiles.
With dialer profiles, you are effectively moving some of the logical ISDN parameters
from the physical BRI/PRI interface to a dialer interface. Any IP packet should
represent ‘interesting traffic’ in this lab and either router should be able to initiate the
call. PPP encapsulation and CHAP authentication should be used. Refer to the table
above for ISDN switch-type, IP addresses, subnet masks, and telephone numbers.
router1(config)# isdn switch-type basic-ni
router1(config)# dialer-list 1 protocol ip permit
router1(config)# username router2 password cisco
router1(config)# interface bri0
router1(config-if)# encap ppp
router1(config-if)# ppp authentication chap
router1(config-if)# isdn spid1 32177820010100
router1(config-if)# dialer pool-member 1

2. Issue the show isdn status command on both router1 and router2. You should see:
Layer1: Active
Layer2: Multiple Frame Established with spid1 valid.
routerx# show isdn status
3. Issue the show interfaces bri0 command on router1. This displays the signaling or D
Channel. It should show ‘Up and Up (spoofing)’ if it is ready to handle a call request.
Now issue the command show interfaces bri0 1 2. This should show the status of the two
data, or B channels.
router1# show interfaces bri0
router1# show interfaces bri0 1 2
4. From router1, ping the ISDN interface of router2. This should cause an ISDN call to
be initiated and the pings should succeed.
router1# ping 200.10.1.2
6. Issue the show isdn status command on router1. Under the Layer 3 status in the
output, it should show one call active.
router1# show isdn status
7. Issue the show interfaces bri0 1 2 command on router1. This shows the status of the B
channels (data channels). One of the B channels should have a status of ‘UP and UP’
indicating a successful call is in progress.
router1# show interfaces bri0 1 2

LAB 19 – ISDN PRI using Dialer Profiles
Router IP Address Mask SPID1 Local Tel# ISDN Switch
router1 201.10.1.1 /24 32177820010100 7782001 basic-ni
router2 201.10.1.2 /24 ----- 7782002 primary-5ess
1. In this lab, you will configure ISDN BRI on router1 and ISDN PRI on router2 using
dialer profiles. Router2 has a primary rate ISDN interface (S0/0) as well as a basic rate
ISDN interface. Any IP packet should represent ‘interesting traffic’ in this lab and either
router should be able to initiate the call. PPP encapsulation and CHAP authentication
should be used. Refer to the table above for ISDN switch-type, IP addresses, subnet
masks, and telephone numbers.
a. Question: if this PRI was being configured in Europe, what would the options be for
controller type, framing, and linecode?
b. Question: On the PRI interface statement, what is the significance of: 23

2. Issue the show isdn status command on both router1 and router2. You should see:
Layer1: Active

routerx# show isdn status
3. From router1, ping the ISDN interface of router2. This should cause an ISDN call to
be initiated and the pings should succeed.
router1# ping 201.10.1.2
4. Issue the show isdn status command on router1. Under the Layer 3 status in the
output, it should show one call active.
router1# show isdn status
5. Issue the show interfaces bri0 1 2 command on router1. This shows the status of the
B channels (data channels). One of the B channels should
have a status of ‘UP and UP’ indicating a successful call is in progress.

LAB 20 – FRAME RELAY
Router Interface IP Address Local DLCI
router1 serial 1 215.10.1.1 /24 105
router5 serial 0 215.10.1.2 /24 501
1. In this lab, you will set up frame relay PVC’s between router1 and router5 using both
physical interfaces and point-to-point sub interfaces. Both routers will be frame relay
DTE devices connected to a frame relay cloud.
2. Using physical interfaces (no sub interfaces), configure frame relay on router1’s serial1
interface and router5’s serial0 interface. Refer to the chart above for IP addresses and
local DLCI’s. Both routers will use ANSI as their lmi-type. Frame relay map statements
should be used for static mapping.
a. Question: what is the default lmi-type on Cisco routers?
router1(config)# interface serial1
router1(config-if)# encapsulation frame-relay
router1(config-if)# ip address 215.10.1.1 255.255.255.0
router1(config-if)# frame-relay map ip 215.10.1.2 105 broadcast
router1(config-if)# frame-relay lmi-type ansi
router1(config-if)# no shut
router5(config)# interface serial0
router5(config-if)# encapsulation frame-relay
router5(config-if)# ip address 215.10.1.2 255.255.255.0
router5(config-if)# frame-relay map ip 215.10.1.1 501 broadcast
router5(config-if)# frame-relay lmi-type ansi
router5(config-if)# no shut
3. Issue the show interfaces serial x command on both router1 and router5. This will
show if the routers are successfully connected to their local frame relay switches. The
status on the first line should be ‘up and line protocol is up’. On the fifth line of output,
you should also see ‘DTE LMI up’. The encapsulation type should be frame relay.
router1# show interfaces serial1
router5# show interfaces serial0
4. Issue the show frame-relay map command on router1 and router5. This will show the
mapping of local DLCI’s to remote IP addresses.
routerx# show frame-relay map
5. Issue the show frame-relay pvc command on router1 and router5. This will show the
status of the PVC’s connected to the routers. You want to
see a status of ‘active’ which indicates the PVC is operational end-to-end.

cấu hình cổng ISDN trên Cisco routers có một số điểm cần lưu ý như sau:

Câu lệnh khai báo loại tổng đài ISDN switch-type phải thực hiện trên mode interface và trên chế độ toàn cục .

Câu lệnh khai báo giá trị spid có thể phụ thuộc vào loại tồng đài đang được dùng .

Các thông số của ppp như ppp multilink, authentication, callback...phải được cấu hình tương ứng ở hai đầu . Nếu chỉ một đầu router thực hiện thì PPP sẽ không chạy

ISDN vẫn hỗ trợ HDLC trên kênh B nhưng rất ít dùng .
