10 Low-speed ATM configuration

Nortel Secure Router 8000 Series

Configuration -WAN Access

10-44 Nortel Networks Inc. Issue 5.3 (

30 March 2009)

Configuration procedure

Step 1 Configure local users for PPP authentication and create an IP local address pool on Router C.

<RouterC> system-view

[RouterC] aaa

[RouterC-aaa] local-user user1 password simple pwd1

[RouterC-aaa] local-user user2 password simple pwd2

[RouterC-aaa] ip pool 1 202.38.162.1 202.38.162.100

Step 2 Create a VT interface, configure PAP authentication and IP address, and assign an IP address

from the IP address pool for the peer.

[RouterC] interface virtual-template 10

[RouterC-Virtual-Template10] ip address 202.38.160.1 255.255.255.0

[RouterC-Virtual-Template10] ppp authentication-mode pap

[RouterC-Virtual-Template10] remote address pool 1

[RouterC-Virtual-Template10] quit

[RouterC] interface virtual-template 11

[RouterC-Virtual-Template11] ip address 202.38.161.1 255.255.255.0

[RouterC-Virtual-Template11] ppp authentication-mode pap

[RouterC-Virtual-Template11] remote address pool 1

[RouterC-Virtual-Template11] quit

Step 3 Create PVC that is specified to carry PPP.

[RouterC] interface atm 1/0/0.1

[RouterC-Atm1/0/0.1] pvc to_adsl_a 0/60

[RouterC-atm-pvc-Atm1/0/0.1-0/60-to_adsl_a] map ppp virtual-template 10

[RouterC-atm-pvc-Atm1/0/0.1-0/60-to_adsl_a] quit

[RouterC-Atm1/0/0.1] pvc to_adsl_b 0/61

[RouterC-atm-pvc-Atm1/0/0.1-0/61-to_adsl_b] map ppp virtual-template 11

[RouterC-atm-pvc-Atm1/0/0.1-0/61-to_adsl_b] quit

Step 4 Configure reachable routes between Router A, Router B and Router C.

Step 5 Verify the configuration.

# Check the PVC status on Router C.

[RouterC] display atm pvc-info

--------|-----|----------------|--------|-----|-----|---------------------

0/60 |UP |to_adsl_a |60 |SNAP |PPP |Atm1/0/0 (UP)

0/61 |UP |to_adsl_b |61 |SNAP |PPP |Atm1/0/0 (UP)

Set up a PPP connection to ADSL Router and the authentication succeeds. You can ping PCs

attached to Router A and Router B through the interfaces of Router C.
