To enable IP directed broadcast for a specified subnet:
1.
Add the target subnet’s logical interfaces to the VLAN:
[edit interfaces]
user@switch#
set ge-0/0/0.0 family ethernet-switching vlan members v1
user@switch#
set ge-0/0/1.0 family ethernet-switching vlan members v1
2.
Configure the Layer 3 interface on the VLAN that is the target of the IP directed
broadcast packets:
[edit interfaces]
user@switch#
set vlan.1 family inet address 10.1.2.1/24
3.
Associate a Layer 3 interface with the VLAN:
[edit vlans]
user@switch#
set v1
l3-interface
vlan.1
4.
Enable the Layer 3 interface for the VLAN to receive IP directed broadcasts:
[edit interfaces]
user@switch#
set vlan.1 family inet
targeted-broadcast

Configuring a Layer 3 Subinterface (CLI Procedure)
EX Series switches use Layer 3 subinterfaces to divide a physical interface into multiple
logical interfaces, each corresponding to a VLAN. The switch uses the Layer 3
subinterfaces to route traffic between subnets.
To configure Layer 3 subinterfaces, you enable VLAN tagging and partition one or more
physical ports into multiple logical interfaces, each corresponding to a VLAN ID.
Before you begin, make sure you set up your VLANs. See “Configuring VLANs for EX Series
Switches (CLI Procedure)” on page 1378 or “Configuring VLANs for EX Series Switches
(J-Web Procedure)” on page 1375.
To configure Layer 3 subinterfaces:
1.
Enable VLAN tagging:
[edit interfaces
interface-name
]
user@switch#
set
vlan-tagging
2.
Bind each VLAN ID to a logical interface:
[edit interfaces
interface-name
]
user@switch#
set unit logical-unit-number
vlan-id
vlan-id-number
