4.7.1 Example for directly connecting routers through POS
interfaces
Networking requirements
You need to directly connect the POS interfaces of Router A and Router B with a pair of
single mode optic fiber (receiving, sending) through PPP.

Configuration roadmap
The configuration roadmap is as follows:
1. Configure the link layer protocol to PPP.
2. Configure the IP address.
Data preparation
To connect routers directly through POS interfaces, you need the following data:
• The IP address of POS 1/0/0 of Router A is 10.110.1.10/24.
• The IP address of POS 4/0/0 of Router A is 10.110.1.11/24.
Configuration procedure
