Data preparation
To connect LANs through the private line, you need the following data:
# The IP addresses of each interface and the VC number is shown in Figure 8-6.
# Router A works in the DCE mode.
# Router B works in the DTE mode.
Configuration procedure
Step 1 Configure Router A.
# Encapsulate the interface with FR.
system-view
[RouterA] interface serial 1/0/0
[RouterA-Serial1/0/0] ip address 202.38.163.251 255.255.255.0
[RouterA-Serial1/0/0] link-protocol fr
[RouterA-Serial1/0/0] fr interface-type dce
[RouterA-Serial1/0/0] fr dlci 100
[RouterA-fr-dlci-Serial1/0/0-100] quit
# Configure dynamic address mapping if the opposite router supports reverse address
resolution function.
[RouterA-Serial1/0/0] fr inarp
# Otherwise, configure static address mapping.
[RouterA-Serial1/0/0] fr map ip 202.38.163.252 100
Step 2 Configure Router B.
# Encapsulate the interface with FR.
system-view
[RouterB] interface serial 1/0/0
[RouterB-Serial1/0/0] ip address 202.38.163.252 255.255.255.0
[RouterB-Serial1/0/0] link-protocol fr
[RouterB-Serial1/0/0] fr interface-type dte
# Configure dynamic address mapping if the opposite router supports reverse address
resolution function.
[RouterB-Serial1/0/0] fr inarp
# Otherwise, configure static address mapping.
[RouterB-Serial1/0/0] fr map ip 202.38.163.251 100
Step 3 Verify the configuration.
Display the FR address mapping on Router B. In the following example, the FR interface
learns the peer DLCI through dynamic address mapping.
[RouterB] display fr map-info interface Serial 1/0/0
