Configuration roadmap
The configuration roadmap is as follows:
1.
Configure link protocol of the interface that accesses the FR network to FR.
2.
Configure sub-interfaces and allocate IP addresses and VC.
3.
Configure the static route to the opposite LAN.
Data preparation
To configure the sub-interface, you need the following data:
•
On Router A, the number of the interface that accesses the FR network is Serial 1/0/0:0.
•
IP addresses of two sub-interfaces on Router A are 202.38.160.1 and 202.38.161.1
respectively.
•
DLCIs that connect Router A to the FR network are 50 and 60 respectively.
•
Network addresses of three LANs are shown in Figure 5-1.
•
On Router B and Router C, the IP addresses of the interfaces that access the FR network
are 202.38.160.2 and 202.38.161.2 respectively.
Configuration procedure
Step 1
Configure Router A.
• Configure link layer protocol as FR on Serial 1/0/0:0 of Router A.
