Step 3 Configure SwitchC.
# Configure link layer protocol as FR on Serial 1/0/0 of SwitchC.
[HUAWEI] sysname SwitchC
[SwitchC] interface serial 1/0/0
[SwitchC-Serial1/0/0] link-protocol fr
[SwitchC-Serial1/0/0] fr interface-type dte
# Configure the IP address on Serial 1/0/0 of SwitchC, and assign VC for it.

# Configure the static routes from SwitchB to LAN1.
[SwitchC] ip route-static 129.9.0.0 255.255.0.0 202.38.161.2
Check the configuration.
Run the display ip route-table command on SwitchA to view routes of LAN2 and LAN3. The
ping command output shows that three LANs can access each other.
