Placing/Receiving Calls From A Specified Physical Interface - 3Com 3C13636 Configuration Manual

3Com Router 3000 Ethernet Family
Configuration Guide
Solution 2: Adopt C-DCC and use the logical interface configured through the dialer
route command as the main interface.
1) Configure RouterA
[3Com] dialer-rule 1 ip permit
[3Com] interface serial 0/0/0
[3Com-Serial0/0/0] physical-mode async
[3Com-Serial0/0/0] async mode protocol
[3Com-Serial0/0/0] ip address 100.1.1.1 255.255.255.0
[3Com-Serial0/0/0] dialer enable-circular
[3Com-Serial0/0/0] dialer-group 1
[3Com-Serial0/0/0] dialer route ip 100.1.1.2 8810060 logic-channel 1
[3Com-Serial0/0/0] interface serial 1/0/0
[3Com-Serial1/0/0] ip address 200.1.1.1 255.255.255.0
[3Com-Serial1/0/0] link-protocol ppp
[3Com-Serial1/0/0] standby interface logic-channel 1
[3Com-Serial1/0/0] user-interface tty1
[3Com-ui-tty1] modem
2) Configure RouterB
[3Com] dialer-rule 2 ip permit
[3Com] interface serial 0/0/0
[3Com-Serial0/0/0] physical-mode async
[3Com-Serial0/0/0] async mode protocol
[3Com-Serial0/0/0] ip address 100.1.1.2 255.255.255.0
[3Com-Serial0/0/0] dialer enable-circular
[3Com-Serial0/0/0] dialer-group 2
[3Com-Serial0/0/0] dialer route ip 100.1.1.1 8810059 logic-channel 1
[3Com-Serial0/0/0] interface serial 1/0/0
[3Com-Serial1/0/0] ip address 200.1.1.2 255.255.255.0
[3Com-Serial1/0/0] link-protocol ppp
[3Com-Serial1/0/0] standby interface logic-channel 1
[3Com-Serial1/0/0] user-interface tty1
[3Com-ui-tty1] modem

1.4.9 Placing/Receiving Calls from a Specified Physical Interface

I. Network requirements
As shown in the following network diagram, Router A uses IP address 22.0.0.1. Its
interfaces BRI 0/0/0 and PRI 1/0/0 are connected to different ISDN switches, but both
are assigned to interface Dialer 0. BRI 0/0/0 and PRI 1/0/0 are associated with
telephone numbers 7300340 and 8500560 respectively.
Router B uses IP address 22.0.0.2. Its interfaces BRI 0/0/0 and PRI 1/0/0 are
connected to the same ISDN switch and both are assigned to interface Dialer 0. BRI
