Figure 126 Networking diagram of the static route configuration example
Configuration procedure
1 Configure the static route for Ethernet Switch A
[ Switch A] ip route-static 1.1.3.0 255.255.255.0 1.1.2.2
[ Switch A] ip route-static 1.1.4.0 255.255.255.0 1.1.2.2
[ Switch A] ip route-static 1.1.5.0 255.255.255.0 1.1.2.2
2 Configure the static route for Ethernet Switch B
[ Switch B] ip route-static 1.1.2.0 255.255.255.0 1.1.3.1
[ Switch B] ip route-static 1.1.5.0 255.255.255.0 1.1.3.1
[ Switch B] ip route-static 1.1.1.0 255.255.255.0 1.1.3.1
3 Configure the static route for Ethernet Switch C
[ Switch C] ip route-static 1.1.1.0 255.255.255.0 1.1.2.1
[ Switch C] ip route-static 1.1.4.0 255.255.255.0 1.1.3.2
4 Configure the default gateway of the Host A to be 1.1.5.1
5 Configure the default gateway of the Host B to be 1.1.4.1
6 Configure the default gateway of the Host C to be 1.1.1.1
By then, all the hosts or Ethernet Switches in the figure can be interconnected in
pairs.
Static Route Fault
Diagnosis and
Troubleshooting
Fault: the S4200G Series Ethernet Switch is not configured with the dynamic routing
protocol and both the physical status and the link layer protocol status of the
interface is UP, but the IP packets cannot be forwarded normally.
Troubleshooting:
■ Use the display ip routing-table protocol static command to view whether the
corresponding static route is correctly configured.
■ Use the display ip routing-table command to view whether the corresponding
route is valid.
