Configuration procedure
1. Configure Router A:
<RouterA> system-view
[RouterA] interface bri 2/0
[RouterA-Bri2/0] link-protocol ppp
[RouterA-Bri2/0] ppp mp virtual-template 5
[RouterA-Bri2/0] dialer enable-circular
[RouterA-Bri2/0] dialer isdn-leased 0
[RouterA-Bri2/0] dialer isdn-leased 1
[RouterA-Bri2/0] quit
[RouterA] interface virtual-template 5
[RouterA-Virtual-Template5] ip address 202.38.154.1 255.255.0.0
2. Configure Router B:
<RouterB> system-view
[RouterB] interface bri2/0
[RouterB-Bri2/0] link-protocol ppp
[RouterB-Bri2/0] ppp mp virtual-template 5
[RouterB-Bri2/0] dialer enable-circular
[RouterB-Bri2/0] dialer isdn-leased 0
[RouterB-Bri2/0] dialer isdn-leased 1
[RouterB-Bri2/0] quit
[RouterB] interface virtual-template 5
[RouterB-Virtual-Template5] ip address 202.38.154.2 255.255.0.0
Only virtual-templates can be used as the MP binding templates for ISDN leased lines.
As leased lines do not require dialing, you do not need to configure dial numbers.
The system accepts MP bundles formed by 64-kbps, 128-kbps ISDN leased lines or a mix of both.
For more information, see the three ways to configure MP bundles discussed in "Configuring PPP
and MP."
Configuring ISDN 128K leased lines
Network requirements
As shown in Figure 21, Router A and Router B are connected by connecting their ISDN BRI
interfaces through a 128K leased line.
