A Segment DHCP server provides a dynamic IP assignment service only to the VMs that are attached to the NSX segment. NSX supports Segment DHCP server configuration on the downlink interface and the service interface.
You can configure a Segment DHCPv4 server, or a Segment DHCPv6 server, or both, on the segment.
The following figure shows a sample network topology that has a Segment DHCP server configured on four networks.
In this network topology, a Segment DHCP server is configured on the following networks:
- Network-2 is connected to the downlink interface of tier-1 gateway.
- Network-1 is connected to the service interface of tier-0 gateway.
- Network-4 is connected to the service interface of tier-1 gateway.
- Network-3 is an isolated segment, which is not connected to any gateway.
