Configuration procedure
1 Configure Router A
<RouterA> system-view
[RouterA] dialer-rule 1 ip permit
[RouterA] interface bri 2/0
[RouterA-Bri2/0] ip address 100.1.1.1 255.255.255.0
[RouterA-Bri2/0] link-protocol ppp
[RouterA-Bri2/0] dialer enable-circular
[RouterA-Bri2/0] dialer-group 1
[RouterA-Bri2/0] dialer isdn-leased 128k
2 Configure Router B
<RouterB> system-view
[RouterB] dialer-rule 1 ip permit
[RouterB] interface bri 2/0
[RouterB-Bri2/0] ip address 100.1.1.2 255.255.255.0
[RouterA-Bri2/0] link-protocol ppp
[RouterB-Bri2/0] dialer enable-circular
[RouterB-Bri2/0] dialer-group 1
[RouterB-Bri2/0] dialer isdn-leased 128k
You do not need to configure a dial number because setup of leased line
connection does not involve dial process.
After you configure a lease line successfully, you can dial through. To view state
about the interfaces, execute the following commands:
<RouterA> display interface bri 2/0
Bri2/0 current state :UP
Line protocol current state :UP (spoofing)
