Configuration procedure
1 Configure Router A:
# Assign an IP address to Serial 2/0 interface.
<RouterA> system-view
[RouterA] interface serial 2/0
[RouterA-Serial2/0] ip address 202.38.163.251 255.255.255.0
# Configure interface encapsulation protocol as frame relay.
[RouterA-Serial2/0] link-protocol fr
[RouterA-Serial2/0] fr interface-type dte
# If the opposite router supports InARP, configure dynamic address mapping.
[RouterA-Serial2/0] fr inarp
# Otherwise, configure static address mapping.
[RouterA-Serial2/0] fr map ip 202.38.163.252 50
[RouterA-Serial2/0] fr map ip 202.38.163.253 60
2 Configure Router B:
# Assign an IP address.
<RouterB> system-view
[RouterB] interface serial 2/0
[RouterB-Serial2/0] ip address 202.38.163.252 255.255.255.0
# Configure interface encapsulation protocol as frame relay.
[RouterB-Serial2/0] link-protocol fr
