<RouterB> system-view
[RouterB] interface pos 1/0/1
[RouterB-Pos1/0/1] link-protocol hdlc
[RouterB-Pos1/0/1] ip address 12.1.1.2 24
After the configuration, Router A and Router B should be able to ping each other. Take the output
on Router A as an example.
[RouterA] ping 12.1.1.2

configuration example
Network requirements
As shown in Figure 32, Router A and Router B are connected through their POS ports with HDLC enabled.
Configure POS 1/0/1 of Router A to borrow the IP address of the local loopback interface, whose IP
address has a 32-bit mask.
Configure Router A to learn the routing information of Router B through static routes, so that Router A can
reach the network segment 12.1.2.0/24.

Configuration procedure
1. Configure Router A:
<RouterA> system-view
[RouterA] interface loopback 1
[RouterA-LoopBack1] ip address 12.1.1.2 32
[RouterA-LoopBack1] quit
[RouterA] interface pos 1/0/1
[RouterA-Pos1/0/1] clock master
[RouterA-Pos1/0/1] link-protocol hdlc
[RouterA-Pos1/0/1] ip address unnumbered interface loopback 1
