a Add a user for Router B and Router C respectively

[3Com]local-user router-b password simple router-b

[3Com]local-user router-c password simple router-c

b Specify the virtual-templates for the two users and begin PPP negotiation by

using the NCP information of the virtual-templates.

[3Com]ppp mp user router-b bind virtual-template 1

[3Com]ppp mp user router-c bind virtual-template 2

c Configure the virtual-templates

[3Com]interface virtual-template 1

[3Com-virtual-template1]ip address 202.38.166.1 255.255.255.0

[3Com]interface virtual-template 2

[3Com-virtual-template2]ip address 202.38.168.1 255.255.255.0

d Add the interfaces serial2/0/0:1, serial2/0/0:2, serial2/0/0:3, and serial2/0/0:4

into the MP channel. Here, Serial2/0/0:1 is taken as an example, and you may
add other interfaces in the same way.

[3Com]interface serial 2/0/0:1

[3Com-Serial2/0/0:1]link-protocol ppp
