Statement introduced in Junos OS Release 17.2 on MX Series routers.
(MPC5 and MPC6 cards) Improve datapath performance by allowing only DHCPv4 subscribers that negotiate a 32-bit prefix to come up on the underlying VLAN interface. All DHCP subscribers on the underlying interface must negotiate a 32-bit prefix. Subscribers that negotiate a subnet prefix are not brought up. You can configure this statement for static or dynamic subscribers.
You must add or remove this statement before subscribers become active. The configuration fails if you attempt to configure the statement while subscribers are active.
You must also configure demux-source inet for the logical interface. Only inet is supported. A commit error occurs if you specify demux-source inet6 or demux-source [inet inet6].
