Introduction

The following information describes how to enable multiple networks on a switch to access the public network through the router.

Prerequisites

This document is not restricted to specific software or hardware versions. Procedures and information in the examples might be slightly different depending on the software or hardware version of the device.

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of VLAN and static routing.

Network configuration

As shown in Figure 1, Host A and Host B are connected to the switch. Host A belongs to VLAN 2, and Host B belongs to VLAN 3. The IP addresses for interfaces VLAN-interface 1, VLAN-interface 2, and VLAN-interface 3 on the switch are 192.168.1.254/24, 192.168.2.1/24, and 192.168.3.1/24, respectively. The IP address for interface VLAN-interface 1 on the device is 192.168.1.1/24. Configure network settings for Host A and Host B to access the Internet.

Software version used

This document applies to Comware 7-based MER router series. This configuration example was created and verified on R6749P14 of the MER8300 router.

Procedures

1. Configuring Host A and Host B

Set the IP address of the Host A to 192.168.2.2/24, and set its gateway address to 192.168.2.1/24. Set the IP address of the Host B to 192.168.3.2/24, and set its gateway address to 192.168.3.1/24.

2. Configuring the switch

# Create VLAN 2 and VLAN 3.

<Switch> system-view

[Switch] vlan 2 to 3

# Assign interface GigabitEthernet 1/0/2 to VLAN 2.

[Switch] interface gigabitethernet 1/0/2

[Switch-GigabitEthernet1/0/2] port access vlan 2

[Switch-GigabitEthernet1/0/2] quit

# Assign interface GigabitEthernet 1/0/3 to VLAN 3.

[Switch] interface gigabitethernet 1/0/3

[Switch-GigabitEthernet1/0/3] port access vlan 3

[Switch-GigabitEthernet1/0/3] quit

# Set the IP address of VLAN-interface 1 to 192.168.1.254/24.

[Switch] interface vlan-interface 1

[Switch-Vlan-interface1] ip address 192.168.1.254 255.255.255.0

[Switch-Vlan-interface1] quit

# Set the IP address of VLAN-interface 2 to 192.168.2.1/24.

[Switch] interface vlan-interface 2

[Switch-Vlan-interface2] ip address 192.168.2.1 255.255.255.0

[Switch-Vlan-interface2] quit

# Set the IP address of VLAN-interface 3 to 192.168.3.1/24.

[Switch] interface vlan-interface 3

[Switch-Vlan-interface3] ip address 192.168.3.1 255.255.255.0

[Switch-Vlan-interface3] quit

# Configure a default route.

<Switch> system-view

[Switch] ip route-static 0.0.0.0 0.0.0.0 192.168.1.1

3. Configuring the device

# Log in to the web management interface of the router. From the left navigation pane, select Network > LAN Settings. Edit interface VLAN-interface 1.
