Directly Connecting
Routers Through POS
Interfaces
n
If a physical interface is idle or has no cable connection, shut down it with the
shutdown command to avoid interface anomalies that may result from
interference. As the command can disable the interface, use it with caution.
Network requirements
Use a pair of single mode optic fiber (respectively for receiving and sending data)
to connect the POS interfaces on Router A and Router B.
Encapsulate the interfaces with PPP.

Configuration procedure
1 Configure Router A
# Configure interface POS 1/0, setting its physical parameters to defaults.
<RouterA> system-view
[RouterA] interface pos 1/0
[RouterA-Pos1/0] ip address 10.110.1.10 255.255.255.0
[RouterA-Pos1/0] link-protocol ppp
[RouterA-Pos1/0] mtu 1500
[RouterA-Pos1/0] shutdown
[RouterA-Pos1/0] undo shutdown
2 Configure Router B
# Configure interface POS 1/0.
<RouterB> system-view
[RouterB] interface pos 1/0
# Set the clock mode to master and other physical parameters to defaults.
[RouterB-Pos1/0] clock master
[RouterB-Pos1/0] ip address 10.110.1.11 255.255.255.0
[RouterB-Pos1/0] link-protocol ppp
[RouterB-Pos1/0] mtu 1500
[RouterB-Pos1/0] shutdown
[RouterB-Pos1/0] undo shutdown
You can check the interface connectivity between the POS interfaces with the
display interface pos command and test network connectivity with the ping
command.
