MP binding mode configuration examples
Network requirements
As shown in Figure 9, to enable MP for Serial 2/1/0 and Serial 2/1/1, use one of the following methods:
Bind the physical interfaces to a VT interface.
Associate remote usernames with a VT interface.
Configure an MP-group interface.

Configuration procedure
(Method 1) Binding the physical interfaces to a VT interface
Configure Router A:
# Create a VT interface, and configure an IP address for it.
<RouterA> system-view [RouterA] interface virtual-template 1 [RouterA-Virtual-Template1] ip address 8.1.1.1 24 [RouterA-Virtual-Template1] quit
# Configure Serial 2/1/1.
[RouterA] interface serial 2/1/1 [RouterA-Serial2/1/1] link-protocol ppp [RouterA-Serial2/1/1] ppp mp virtual-template 1 [RouterA-Serial2/1/1] quit
# Configure Serial 2/1/0.
[RouterA] interface serial 2/1/0 [RouterA-Serial2/1/0] link-protocol ppp [RouterA-Serial2/1/0] ppp mp virtual-template 1 [RouterA-Serial2/1/0] quit
Configure Router B:
# Create a VT interface, and configure an IP address for it.
<RouterB> system-view [RouterB] interface virtual-template 1 [RouterB-Virtual-Template1] ip address 8.1.1.2 24 [RouterB-Virtual-Template1] quit
# Configure Serial 2/1/1.
[RouterB] interface serial 2/1/1 [RouterB-Serial2/1/1] link-protocol ppp [RouterB-Serial2/1/1] ppp mp virtual-template 1 [RouterB-Serial2/1/1] quit
# Configure Serial 2/1/0.
[RouterB] interface serial 2/1/0 [RouterB-Serial2/1/0] link-protocol ppp [RouterB-Serial2/1/0] ppp mp virtual-template 1 [RouterB-Serial2/1/0] quit
Verify the configuration:
