Configuring VLANs over Bridged Ethernet
This section describes how to create the following common static VLAN over bridged
Ethernet configurations:
■
IP over VLAN over bridged Ethernet
■
PPPoE over VLAN over bridged Ethernet
■
MPLS over VLAN over bridged Ethernet
You can also configure transparent bridging over VLANs over bridged Ethernet. For
information about configuring transparent bridging, see “Configuring Bridged
Ethernet” on page 443.
Configuring VLANs over bridged Ethernet interfaces consists of two basic tasks:
1.
Configure the layers up to and including the VLAN subinterface. The steps for
this task are common to all configurations.
2.
Configure the higher-level protocols above the VLAN subinterface.
The following sections describe how to configure VLANs over bridged Ethernet. For
more information about the commands used in these procedures, see the command
descriptions listed in alphabetical order at the end of “Configuring Higher-Level
Protocols over VLANs” on page 454.
NOTE: Before you can remove a VLAN subinterface, you must remove the upper-layer
interface stack.
For more information about specifying ATM interfaces and subinterfaces, see Interface
Types and Specifiers in
JUNOSe Command Reference Guide .
Configuring VLAN Subinterfaces over Bridged Ethernet
To configure a VLAN subinterface over bridged Ethernet:
1.
Create an ATM 1483 subinterface and associated PVC.
host1(config)# interface atm 4/0.101
host1(config-subif)# atm pvc 1 0 32 aal5snap 0 0 0
2.
Specify bridged Ethernet as the encapsulation method for the ATM 1483
subinterface.
host1(config-subif)# encapsulation bridge1483
3.
Create a VLAN major interface by specifying VLAN as the encapsulation method
for the bridged Ethernet interface.
host1(config-subif)# encapsulation vlan
