Verifying the configuration
# Verify that the HDLC link bundle interfaces on Router A and Router B can ping each other.

# Verify that:
POS 2/1/1 and POS 2/1/2 are in Selected state and can perform load balancing.
The bandwidth of the HDLC link bundle is 1244160 kbps, the total bandwidth of two POS interfaces.
When one POS interface fails, the traffic can be forwarded through the other POS interface. This improves the link reliability.
Use Router A as an example.
