Usage Scenario
VPNs are specifically constructed for interconnections within an office or between offices. To configure a VPN instance for an IP address pool, run the vpn-instance command.
Prerequisites
A VPN instance has been created using the ip vpn-instance command.
Precautions
A DHCP client can go online through the DHCP server only when the VPN instance bound to the DHCP server address pool is the same as that bound to the DHCP relay server group.
