Usage Guidelines

Usage Scenario

This command applies to DHCP relay agents. To apply DHCP services in a VPN instance, you need to run the vpn-instance command to bind the created DHCP server group to the VPN instance.

Prerequisites

A VPN instance has been created using the ip vpn-instance command.

Precautions

The VPN instance bound to the DHCP server group on the DHCP relay agent must be the same as the VPN instance bound to the IP address pool on the DHCP server; otherwise, users in the IP address pool cannot go online.

Example

# Bind DHCP server group dhcp-srv1 to VPN instance huawei.

<HUAWEI> system-view
[HUAWEI] ip vpn-instance huawei
[HUAWEI-vpn-instance-huawei] ipv4-family
[HUAWEI-vpn-instance-huawei-af-ipv4] route-distinguisher 22:1
[HUAWEI-vpn-instance-huawei-af-ipv4] quit
[HUAWEI-vpn-instance-huawei] quit
[HUAWEI] dhcp server group dhcp-srv1
