Example for Configuring IPv4 Static Routes

Procedure

1. Create VLANs and add interfaces to the VLANs.

   # Configure SwitchA. The configurations of SwitchB and SwitchC are similar to the configuration of SwitchA.

   <HUAWEI> system-view
   [HUAWEI] sysname SwitchA
   [SwitchA] vlan batch 10 30
   [SwitchA] interface gigabitethernet 0/0/1
   [SwitchA-GigabitEthernet0/0/1] port link-type trunk
   [SwitchA-GigabitEthernet0/0/1] port trunk allow-pass vlan 10
   [SwitchA-GigabitEthernet0/0/1] quit
   [SwitchA] interface gigabitethernet 0/0/2
   [SwitchA-GigabitEthernet0/0/2] port link-type access
   [SwitchA-GigabitEthernet0/0/2] port default vlan 30
   [SwitchA-GigabitEthernet0/0/2] quit

2. Assign IPv4 addresses to VLANIF interfaces.

   # Configure SwitchA. The configurations of SwitchB and SwitchC are similar to the configuration of SwitchA.

   [SwitchA] interface vlanif 10
   [SwitchA-Vlanif10] ip address 10.1.4.1 30
   [SwitchA-Vlanif10] quit
   [SwitchA] interface vlanif 30
   [SwitchA-Vlanif30] ip address 10.1.1.1 24
   [SwitchA-Vlanif30] quit

3. Configure PCs.

   Set the default gateway addresses of PC1, PC2, and PC3 to 10.1.1.1, 10.1.2.1, and 10.1.3.1 respectively.

4. Configure IPv4 static routes.

   # Configure a default IPv4 static route on SwitchA.

   [SwitchA] ip route-static 0.0.0.0 0.0.0.0 10.1.4.2

   # Configure two IPv4 static routes on SwitchB.

   [SwitchB] ip route-static 10.1.1.0 255.255.255.0 10.1.4.1
   [SwitchB] ip route-static 10.1.3.0 255.255.255.0 10.1.4.6

   # Configure a default IPv4 static route on SwitchC.

   [SwitchC] ip route-static 0.0.0.0 0.0.0.0 10.1.4.5

5. Verify the configuration.

   # Check the IP routing table on SwitchA.

   [SwitchA] display ip routing-table
   Route Flags: R - relay, D - download to fib, T - to vpn-instance
   ------------------------------------------------------------------------------

           10.1.1.0/24  Direct 0    0         D    10.1.1.1     Vlanif30
           10.1.1.1/32  Direct 0    0         D    127.0.0.1    Vlanif30
           10.1.4.0/30  Direct 0    0         D    10.1.4.1     Vlanif10
           10.1.4.1/32  Direct 0    0         D    127.0.0.1    Vlanif10
         127.0.0.0/8    Direct 0    0         D    127.0.0.1    InLoopBack0
         127.0.0.1/32   Direct 0    0         D    127.0.0.1    InLoopBack0
   

   # Run the ping command to verify the connectivity.

   [SwitchA] ping 10.1.3.1
     PING 10.1.3.1: 56  data bytes, press CTRL_C to break
       Reply from 10.1.3.1: bytes=56 Sequence=1 ttl=253 time=62 ms

   # Run the tracert command to verify the connectivity.

   [SwitchA] tracert 10.1.3.1
