DCC Configuration Example 205
# Assign an IP address to interface Dialer0 and configure it to assign IP addresses
for PPP users.
[RouterB] interface dialer 0
[RouterB-Dialer0] link-protocol ppp
[RouterB-Dialer0] ppp authentication-mode pap
[RouterB-Dialer0] ppp pap local-user userb password simple userb
[RouterB-Dialer0] ip address 100.1.1.254 255.255.255.0
[RouterB-Dialer0] remote address pool 1
# Enable C-DCC and configure C-DCC parameters on the interface.
[RouterB-Dialer0] dialer enable-circular
[RouterB-Dialer0] dialer-group 2
[RouterB-Dialer0] quit
# Configure physical and link layer parameters for interface Async 1/0.
[RouterB] interface async 1/0
[RouterB-Async1/0] async mode protocol
[RouterB-Async1/0] dialer circular-group 0
[RouterB-Async1/0] link-protocol ppp
[RouterB-Async1/0] ppp authentication-mode pap
[RouterB-Async1/0] ppp pap local-user userb password simple userb
[RouterB-Async1/0] quit
Repeat this step to configure physical and link layer parameters for interfaces
Async 1/1 through Async 1/7.
# Configure user interfaces TTY 1 through TTY 7 for interfaces Async 1/0 through
Async 1/7 and enable modem dialup on them.
[RouterB] user-interface tty1
[RouterB-ui-tty1] modem both
[RouterB-ui-tty1] quit
[RouterB] user-interface tty2
[RouterB-ui-tty2] modem both
...
[RouterB-ui-tty8] quit
# Configure the address for address assignment.
[RouterB] domain system
[RouterB-isp-system] ip pool 1 100.1.1.1 100.1.1.16
[RouterB-isp-system] quit
