3Com WX3000 Troubleshooting a Static Route, # Approach 2 Configure a static route on Switch a

Configuration procedure

When only one interface of the device is interconnected with another network segment, you can implement network communication by configuring either a static route or default route.

1)Perform the following configurations on the device.

# Approach 1: Configure static routes on Switch A.

<SwitchA> system-view

[SwitchA] ip route-static 1.1.3.0 255.255.255.0 1.1.2.2

[SwitchA] ip route-static 1.1.4.0 255.255.255.0 1.1.2.2

[SwitchA] ip route-static 1.1.5.0 255.255.255.0 1.1.2.2

# Approach 2: Configure a static route on Switch A.

<SwitchA> system-view

[SwitchA] ip route-static 0.0.0.0 0.0.0.0 1.1.2.2

# Approach 1: Configure static routes on Switch B.

<SwitchB> system-view

[SwitchB] ip route-static 1.1.2.0 255.255.255.0 1.1.3.1

[SwitchB] ip route-static 1.1.5.0 255.255.255.0 1.1.3.1

[SwitchB] ip route-static 1.1.1.0 255.255.255.0 1.1.3.1

# Approach 2: Configure a static route on Switch B.

<SwitchB> system-view

[SwitchB] ip route-static 0.0.0.0 0.0.0.0 1.1.3.1

# Configure static routes on Switch C.

<SwitchC> system-view

[SwitchC] ip route-static 1.1.1.0 255.255.255.0 1.1.2.1

[SwitchC] ip route-static 1.1.4.0 255.255.255.0 1.1.3.2

2)Perform the following configurations on the host.

#Set the default gateway address of Host A to 1.1.5.1. Detailed configuration procedure is omitted.

#Set the default gateway address of Host B to 1.1.4.1. Detailed configuration procedure is omitted.

#Set the default gateway address of Host C to 1.1.1.1. Detailed configuration procedure is omitted. Now, all the hosts and devices in the figure can communicate with each other.

Troubleshooting a Static Route

Symptom: The device is not configured with a dynamic routing protocol. Both the physical status and the link layer protocol status of an interface are up, but IP packets cannot be forwarded on the interface.

Solution: Perform the following procedure.

1)Use the display ip routing-table protocol static command to view whether the corresponding static route is correctly configured.

2)Use the display ip routing-tablecommand to view whether the static route is valid.
