d If the opposite router supports inverse address resolution function, configure 

dynamic address mapping.

[3Com-Serial1/0/0]fr inarp

e Otherwise configure static address mapping.

[3Com-Serial1/0/0]fr map ip 202.38.163.252 100

2 Configure Router B:

a Configure interface IP address.

[3Com]interface serial 1/0/0

[3Com-Serial1/0/0]ip address 202.38.163.252 255.255.255.0

b Configure interface encapsulation as frame relay

[3Com-Serial1/0/0]link-protocol fr

[3Com-Serial1/0/0]fr interface-type dte

c If the opposite router supports inverse address resolution function, configure 

dynamic address mapping.

[3Com-Serial1/0/0]fr inarp

d Otherwise configure static address mapping.

[3Com-Serial1/0/0]fr map ip 202.38.163.251 100

Fault 1: the physical layer in DOWN status.

Check whether the physical line is normal.

Check whether the opposite equipment runs normally.

Fault 2: the physical layer is already UP, but the link layer protocol is DOWN.

Check whether both local equipment and opposite equipment have been 
encapsulated with frame relay protocol.

If two equipments are directly connected, check the local equipment and opposite 
equipment to see whether one end is configured as frame relay DTE interface and 
the other end as frame relay DCE interface.

Please check if the LMI protocol type configuration in the two ends is the same.

If everything is OK, turn on the monitoring switch for the frame relay LMI message 
to see whether one Status Request message correspond to one Status Response 
message. If not, it indicates the physical layer data is not received/sent correctly. 
Check the physical layer. The command

 is used to turn on the 

monitoring switch for frame relay LMI information.

Fault 3: The link layer protocol is UP, but the remote party cannot be pinged.
