Creating a VLAN Subinterface

Creating a VLAN Major Interface

The configuration task examples in this chapter use the format for ERX7xx models,
ERX14xx models, and the ERX310 router to specify a VLAN or S-VLAN subinterface.
For ERX7xx models, ERX14xx models, and ERX310 router, use the slot/port[.subinterface
] format. For example, the following command specifies a VLAN subinterface configured
on port 0 of an I/O module in slot 4.
host1(config)#interface fastEthernet 4/0.1
For E120 and E320 routers, use the slot/adapter/port[.subinterface ] format, which includes
an identifier for the bay in which the I/O adapter (IOA) resides. For example, the following
command specifies a VLAN subinterface configured on port 0 of the IOA installed in the
upper adapter bay of slot 3.
host1(config)#interface gigabitEthernet 3/0/0.1
For more information about interface types and specifiers on E Series models, see Interface
Types and Specifiers in JunosE Command Reference Guide.
For more information about VLAN and S-VLAN implementations, consult the following
resources:
IEEE 802.1q (Virtual LANs)
Ethernet interfaces support IP, PPPoE, MPLS, or both IP and PPPoE on each VLAN. In
addition to a VLAN major interface level, a VLAN subinterface level distinguishes the
VLAN.
NOTE: You cannot configure VLANs on the Fast Ethernet port of the SRP module.
Tasks to configure VLAN subinterface are:
"Creating a VLAN Major Interface" on page 170
"Configuring IP over VLAN" on page 171
"Configuring PPPoE over VLAN" on page 172
"Configuring MPLS over VLAN" on page 173
"Configuring IP over VLAN and PPPoE over VLAN" on page 174
To use VLANs, you must first configure the Ethernet interface for VLAN encapsulation.
This creates the VLAN major interface. For example:
