R3303-HP HSR6800 Routers Interface Configuration Guide

# Configure Serial 2/0/1:0 and Serial2/0/2:0 and assign them to MP-group 1.

[RouterB] interface serial2/0/1:0

[RouterB-Serial2/0/1:0] ppp mp mp-group 1

[RouterB-Serial2/0/1:0] quit

[RouterB] interface serial2/0/2:0

[RouterB-Serial2/0/2:0] ppp mp mp-group 1

[RouterB-Serial2/0/2:0] quit

Verifying the configuration

You can use the display interface serial 2/0/1:0 command, the display interface mp-group 1 command,

and the display ppp mp command to check connectivity, and use the ping command to check network

reachability.

Network requirements

Expand the link bandwidth of Router H and Router B in Figure 15 from 2 Mbps to 32 Mbps. To meet the

requirement, you need at least 16 E1 links. To avoid the complexity of configuring so many E1 links, you

can use an E3 link instead as shown in Figure 16.

Configuration procedure

When connecting the device to a SONET/SDH device, configure the clock mode of the SONET/SDH

device as master, because the clock source of a SONET/SDH network is more precise than the internal

clock source of the device.

1. Configure Router A:

# Configure the E3 channels of CPOS interface CPOS 2/0/0 to operate in unframed mode.

<RouterA> system-view

[RouterA] controller cpos 2/0/0

[RouterA-Cpos2/0/0] using e3 1

[RouterA-Cpos2/0/0] using e3 2

# Configure IP addresses for Serial 2/0/0/1:0 and Serial 2/0/0/2:0.

[RouterA] interface serial2/0/0/1:0

[RouterA-Serial2/0/0/1:0] ip address 11.1.1.2 24

[RouterA-Serial2/0/0/1:0] quit
