CPOS-E1 interface configuration example

Network requirements

As shown in Figure 16, branch nodes Router B through Router H are uplinked to the central node Router

A through E1 links. Router A aggregate these E1 links with a CPOS interface.

Add one more E1 link on Router B to expand its capacity. In addition, bind the two E1 links through an

MP-group interface.

Configuration procedure

IMPORTANT:

For correct network synchronization, make sure the master clock mode is configured on the SONET/SDH

devices connected to the routers.

1. Configure Router A:

# Configure E1 channels 1 and 2 of CPOS 2/0 to operate in unframed mode.

<RouterA> system-view

[RouterA] controller cpos 2/0

[RouterA-Cpos2/0] e1 1 unframed

[RouterA-Cpos2/0] e1 2 unframed

# Create MP-group 1 and assign an IP address to it.

[RouterA] interface mp-group 1

[RouterA-Mp-group1] ip address 10.1.1.1 24

[RouterA-Mp-group1] quit

# Assign Serial 2/0/1:0 to MP-group 1.

[RouterA] interface serial2/0/1:0

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

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

# Assign Serial 2/0/2:0 to MP-group 1.

[RouterA] interface serial2/0/2:0
