Usage guidelines
If a DHCP address pool is applied to a VPN instance, the DHCP server assigns IP addresses in this address pool to clients in the specified VPN instance.
The DHCP server identifies the VPN instance to which a DHCP client belongs according to the following information:
The client's VPN information stored in authentication modules.
The VPN information of the DHCP server's interface that receives DHCP packets from the client.
The VPN information from authentication modules takes priority over the VPN information of the receiving interface.
Examples
# Apply DHCP address pool 0 to VPN instance abc.
<Sysname> system-view [Sysname] dhcp server ip-pool 0 [Sysname-dhcp-pool-0] vpn-instance abc
