Figure 24 Static Route Configuration
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 1.1.5.2
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 1.1.1.2
Using this procedure, all the hosts or switches in Figure 24 can be interconnected
in pairs.
Troubleshooting Static
Routes
The Switch 7750 is not configured with any dynamic routing protocols enabled.
Both the physical status and the link layer protocol status of the interface are
enabled, but the IP packets cannot be forwarded normally.
■ 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.
