Typical Configuration Case of Huawei AR Router - Ethernet Switching

As shown in the figure, an Eth-Trunk is created between DeviceA and DeviceB to bind two Layer 3 Ethernet interfaces into one Eth-Trunk interface, which can increase bandwidth and improve reliability.

Note: In this example, interface1 and interface2 represent 10GE0/0/1 and 10GE0/0/2 respectively.

Steps

Create Eth-Trunk1 on DeviceA and DeviceB and configure IP addresses.

# Configure DeviceA.
```
<HUAWEI> system-view
[HUAWEI] sysname DeviceA
[DeviceA] interface eth-trunk 1
[DeviceA-Eth-Trunk1] undo portswitch
[DeviceA-Eth-Trunk1] ip address 10.1.1.1 24
```
# Configure DeviceB.

<HUAWEI> system-view [HUAWEI] sysname DeviceB [DeviceB] interface eth-trunk 1 [DeviceB-Eth-Trunk1] undo portswitch [DeviceB-Eth-Trunk1] ip address 10.1.1.2 24

Add member interfaces to the Eth-Trunk interfaces of DeviceA and DeviceB.

# Configure DeviceA.

[DeviceB] interface eth-trunk 1
[DeviceA-Eth-Trunk1] port link-type trunk
[DeviceA-Eth-Trunk1] trunkport 10ge 0/0/1 to 0/0/2 
[DeviceA-Eth-Trunk1] quit

# Configure DeviceB.

[DeviceB] interface eth-trunk 1
[DeviceB-Eth-Trunk1] port link-type trunk
[DeviceB-Eth-Trunk1] trunkport 10ge 0/0/1 to 0/0/2 
[DeviceB-Eth-Trunk1] quit

Check configuration results

# Execute the display interface eth-trunk command in any view to check whether the Eth-Trunk is successfully created and whether the member interfaces are correctly added.

VLAN

Example: Configure interface-based VLAN division to achieve intercommunication within the same VLAN (same device)

Networking requirements

As shown in Figure 1-2, assign the interface connecting Host1 and Host2 to VLAN2, and assign the interface connecting Host3 and Host4 to VLAN3, so that hosts in the same VLAN can communicate and hosts in different VLANs cannot communicate directly at Layer 2.

Host1 and Host2 can communicate with each other, and Host3 and Host4 can communicate with each other.
Host1 and Host3 and Host4 in VLAN3 cannot communicate with each other, and Host2 and Host3 and Host4 in VLAN3 cannot communicate with each other.

Figure 1-2 Networking diagram for dividing VLANs based on interfaces (same device)

Note: In this example, interface1, interface2, interface3, and interface4 represent 10GE0/0/1, 10GE0/0/2, 10GE0/0/3, and 10GE0/0/4 respectively.

Steps

Create a VLAN and configure the interface connecting the device to the host as an Access interface.

<HUAWEI> system-view
[HUAWEI] sysname DeviceA

[DeviceA-10GE0/0/4] quit

Configure the interface to join the VLAN.

# Add 10GE0/0/1 and 10GE0/0/2 to VLAN 2.

[DeviceA] vlan 2
[DeviceA-vlan2] port 10ge 0/0/1 to 0/0/2

Example: Configuring a Layer 3 sub-interface to implement communication between different VLANs

Networking requirements

As shown in Figure 1-3, hosts in VLAN2 and VLAN3 are located on different network segments. It is desired to configure a Layer 3 sub-interface on DeviceA to implement communication between hosts in VLAN2 and VLAN3.

Figure 1-3 Networking diagram for intercommunication between different VLANs through Layer 3 sub-interfaces

Note: In this example, interface1, interface2, interface3, and interface4 represent 10GE0/0/1, 10GE0/0/2, 10GE0/0/3, and 10GE0/0/4 respectively.

Steps

Create a VLAN on DeviceB.

<HUAWEI> system-view
[HUAWEI] sysname DeviceB
[DeviceB] vlan batch 2 3
[DeviceB] interface 10ge 0/0/1
[DeviceB-10GE0/0/1] portswitch
[DeviceB-10GE0/0/1] port link-type access
[DeviceB-10GE0/0/1] port default vlan 2
[DeviceB-10GE0/0/1] quit
[DeviceB] interface 10ge 0/0/2
[DeviceB-10GE0/0/2] portswitch
[DeviceB-10GE0/0/2] port link-type access
[DeviceB-10GE0/0/2] port default vlan 3
[DeviceB-10GE0/0/2] quit

Configure interface 10GE0/0/3 on Device B to allow the VLANs that users belong to to pass through.

[DeviceB] interface 10ge 0/0/3
[DeviceB-10GE0/0/3] portswitch
[DeviceB-10GE0/0/3] port link-type trunk
[DeviceB-10GE0/0/3] port trunk allow-pass vlan 2 3
[DeviceB-10GE0/0/3] quit

Create a sub-interface on DeviceA and associate it with a VLAN.

<HUAWEI> system-view
[HUAWEI] sysname DeviceA
[DeviceA] interface 10ge 0/0/4
[DeviceA-10GE0/0/4] undo portswitch
[DeviceA-10GE0/0/4] quit
[DeviceA] interface 10ge 0/0/4.1
[DeviceA-10GE0/0/4.1] dot1q termination vid 2 
[DeviceA-10GE0/0/4.1] quit
[DeviceA] interface 10ge 0/0/4.2
[DeviceA-10GE0/0/4.2] dot1q termination vid 3
[DeviceA-10GE0/0/4.2] quit

Configure an IP address on DeviceA.

[DeviceA] interface 10ge 0/0/4.1
[DeviceA-10GE0/0/4.1] ip address 10.10.10.2 24
[DeviceA-10GE0/0/4.1] quit
[DeviceA] interface 10ge 0/0/4.2
[DeviceA-10GE0/0/4.2] ip address 10.10.20.2 24
[DeviceA-10GE0/0/4.2] quit

Check configuration results

Configure the default gateway on the hosts in VLAN2 to be the IP address 10.10.10.2/24 of interface 10GE0/0/4.1, and configure the default gateway on the hosts in VLAN3 to be the IP address 10.10.20.2/24 of interface 10GE0/0/4.2. After the configuration is complete, hosts in VLAN2 and VLAN3 can ping each other successfully.

Example: Configuring a VLANIF interface to implement intercommunication between different VLANs (same device)

Networking requirements

As shown in Figure 1-4, the hosts under DeviceA are divided into different VLANs, namely VLAN2 and VLAN3, and they are located on different network segments. It is hoped that VLAN2 and VLAN3 can communicate with each other.

Figure 1-4 Network diagram for configuring VLANIF interfaces to implement intercommunication between different VLANs (same device)

Note: In this example, interface1 and interface2 represent 10GE0/0/1 and 10GE0/0/2 respectively.

Steps

Create a VLAN and configure interfaces to join the VLAN.

<HUAWEI> system-view
[HUAWEI] sysname DeviceA
[DeviceA] vlan batch 2 3
[DeviceA] interface 10ge 0/0/1
[DeviceA-10GE0/0/1] portswitch

[DeviceA-10GE0/0/1] port default vlan 2
[DeviceA-10GE0/0/1] quit
[DeviceA] interface 10ge 0/0/2
[DeviceA-10GE0/0/2] portswitch
[DeviceA-10GE0/0/2] port link-type access
[DeviceA-10GE0/0/2] port default vlan 3
[DeviceA-10GE0/0/2] quit

Configure an IP address for the VLANIF interface.

[DeviceA] interface vlanif 2
[DeviceA-Vlanif2] ip address 10.10.10.2 24
[DeviceA-Vlanif2] quit
[DeviceA] interface vlanif 3
[DeviceA-Vlanif3] ip address 10.10.20.2 24
[DeviceA-Vlanif3] quit

Check configuration results

Configure the IP address 10.10.10.1/24 on the host in VLAN2, and configure the default gateway as the IP address 10.10.10.2/24 of interface VLANIF2. Configure the IP address on the host in VLAN3 as 10.10.20.1/24, and the default gateway It is the IP address 10.10.20.2/24 of interface VLANIF3. After the configuration is complete, hosts in VLAN2 and VLAN3 can ping each other successfully.
