MP configuration example

As shown in Figure 8:

• On an E1 interface of Router A, four channels are created with the interface names Serial 2/0:1, Serial 2/0:2, Serial 2/0:3, and Serial 2/0:4.

• On Router B, two channels are created with the interface names Serial 2/0:1 and Serial 2/0:2. It is the same case with Router C.

Do the following:

• Bind two channels on Router A with the two channels on Router B and another two channels with the two channels on Router C.

• Adopt binding authentication.

1. Configure Router A:

   # Create user accounts for Router B and Router C and set the passwords.

   <RouterA> system-view
   [RouterA] local-user router-b
   [RouterA-luser-router-b] password simple router-b
   [RouterA-luser-router-b] service-type ppp
   [RouterA-luser-router-b] quit
   [RouterA] local-user router-c
   [RouterA-luser-router-c] password simple router-c
   [RouterA-luser-router-c] service-type ppp
   [RouterA-luser-router-c] quit
   

   # Create two VT interfaces for the two user accounts.

   [RouterA] ppp mp user router-b bind virtual-template 1
   [RouterA] ppp mp user router-c bind virtual-template 2
   

   # Configure the VT interfaces.

   [RouterA] interface virtual-template 1
   [RouterA-Virtual-Template1] ip address 202.38.166.1 255.255.255.0
   [RouterA-Virtual-Template1] quit
   [RouterA] interface virtual-template 2
   [RouterA-Virtual-Template2] ip address 202.38.168.1 255.255.255.0
   [RouterA-Virtual-Template2] quit
   

   # Add interfaces Serial 2/0:1, Serial 2/0:2, Serial 2/0:3, and Serial 2/0:4 to MP channels. Take Serial 2/0:1 as an example.

   [RouterA] interface serial 2/0:1
   [RouterA-Serial2/0:1] link-protocol ppp
   [RouterA-Serial2/0:1] ppp mp
   [RouterA-Serial2/0:1] ppp authentication-mode pap domain system
   [RouterA-Serial2/0:1] ppp pap local-user router-a password simple router-a
   [RouterA-Serial2/0:1] quit
   

   # Configure local authentication for the PPP users in the default ISP domain system.

   [RouterA] domain system
   [RouterA-isp-system] authentication ppp local
   

2. Configure Router B:

   # Create a user account for Router A.

   <RouterB> system-view
   [RouterB] local-user router-a 
   [RouterB-luser-router-a] password simple router-a
   [RouterB-luser-router-a] service-type ppp
   [RouterB-luser-router-a] quit
   

   # Create a VT interface for the user and specify to use the NCP information of this interface for PPP negotiation.

   [RouterB] ppp mp user router-a bind virtual-template 1
   

   # Configure the VT interface.

   [RouterB] interface virtual-template 1
   [RouterB-Virtual-Template1] ip address 202.38.166.2 255.255.255.0
   [RouterB-Virtual-Template1] quit
   

   # Add interfaces Serial 2/0:1 and Serial 2/0/:2 to the MP channel. Take Serial 2/0:1 as an example.

   [RouterB] interface serial 2/0:1
   [RouterB-Serial2/0:1] ppp mp
   [RouterB-Serial2/0:1] ppp authentication-mode pap domain system
   [RouterB-Serial2/0:1] ppp pap local-user router-b password simple router-b
   [RouterB-Serial2/0:1] quit
   

   # Configure local authentication for the PPP users in the default ISP domain system.

   [RouterB] domain system
   [RouterB-isp-system] authentication ppp local
   

3. Configure Router C:

   # Create a user account for Router A.

   <RouterC> system-view
   [RouterC] local-user router-a
   [RouterC-luser-router-a] password simple router-a
   [RouterC-luser-router-a] service-type ppp
   [RouterC-luser-router-a] quit
   

   # Create a VT interface for the user and specify to use the NCP information of the interface for PPP negotiation.

   [RouterC] ppp mp user router-a bind virtual-template 1
   

   # Configure the VT interface.

   [RouterC] interface virtual-template 1
   [RouterC-Virtual-Template1] ip address 202.38.168.2 255.255.255.0
   [RouterC-Virtual-Template1] quit
   

   # Add interfaces Serial 2/0:1 and Serial 2/0:2 to the MP channel. Take Serial 2/0:1 as an example.

   [RouterC] interface serial 2/0:1
   [RouterC-Serial2/0:1] ppp mp
   [RouterC-Serial2/0:1] ppp authentication-mode pap domain system
   [RouterC-Serial2/0:1] ppp pap local-user router-c password simple router-c
   [RouterC-Serial2/0:1] quit
   

   # Configure local authentication for the PPP users in the default ISP domain system. .

   [RouterC] domain system
   [RouterC-isp-system] authentication ppp local
