Configuration procedure
1. Configure Router A:
# Configure POS interface 3/1/1.
<RouterA> system-view
[RouterA] interface Pos 3/1/1
[RouterA-Pos3/1/1] clock slave
# Configure frame relay encapsulation on the interface.
[RouterA-Pos3/1/1] link-protocol fr
[RouterA-Pos3/1/1] fr interface-type dte
[RouterA-Pos3/1/1] quit
# Create sub-interface 1 on the interface.
[RouterA] interface Pos 3/1/1.1
[RouterA-Pos3/1/1.1] ip address 10.10.10.1 255.255.255.0
[RouterA-Pos3/1/1.1] fr dlci 50
[RouterA-Pos3/1/1.1] fr map ip 10.10.10.2 50
[RouterA-Pos3/1/1.1] mtu 1500
[RouterA-Pos3/1/1.1] quit
# Create sub-interface 2 on the interface.
[RouterA] interface Pos 3/1/1.2
[RouterA-Pos3/1/1.2] ip address 20.10.10.1 255.255.255.0
[RouterA-Pos3/1/1.2] fr dlci 60

[RouterA-Pos3/1/1.2] mtu 1500
[RouterA-Pos3/1/1.2] quit
2. Configure Router B:
# Configure interface POS 3/1/1.
[RouterB] interface Pos 3/1/1
[RouterB-Pos3/1/1] clock slave
# Configure frame relay encapsulation on the interface.
[RouterB-Pos3/1/1] link-protocol fr
[RouterB-Pos3/1/1] fr interface-type dte
[RouterB-Pos3/1/1] ip address 10.10.10.2 255.255.255.0
