Configuring VLAN Subinterfaces over Bridged Ethernet

Configuring Higher-Level Protocols over VLANs

Copyright © 2010, Juniper Networks, Inc.
To configure a VLAN subinterface over bridged Ethernet:
Create an ATM 1483 subinterface and associated PVC.
1.
host1(config)#interface atm 4/0.101
host1(config-subif)#atm pvc 1 0 32 aal5snap 0 0 0
Specify bridged Ethernet as the encapsulation method for the ATM 1483 subinterface.
2.
host1(config-subif)#encapsulation bridge1483
Create a VLAN major interface by specifying VLAN as the encapsulation method for
3.
the bridged Ethernet interface.
host1(config-subif)#encapsulation vlan
Create a VLAN subinterface to carry the higher-level protocols by adding a
4.
subinterface number to the interface identification command.
host1(config-subif)#interface atm 4/0.101.1
Assign a VLAN ID for the subinterface.
5.
host1(config-subif)#vlan id 10
(Optional) Configure additional VLAN subinterfaces by repeating Steps 4 and 5,
6.
using unique values.
host1(config-subif)#interface atm 4/0.101.2
host1(config-subif)#vlan id 11
Proceed to the next section for instructions on configuring higher-level protocols over
the VLAN subinterfaces.
This section provides examples for configuring IP, PPPoE, and MPLS interfaces over VLAN
subinterfaces configured on bridged Ethernet. These procedures assume that you have
already configured one or more VLAN subinterfaces over the bridged Ethernet interface
to carry the higher-level protocols.

Configuring IP over VLAN

To configure IP over VLAN over a bridged Ethernet interface:
Follow the steps in "Configuring VLAN Subinterfaces over Bridged Ethernet" on
1.
page 453 to configure the VLAN subinterface.
Assign an IP address and mask to the VLAN subinterface.
2.
host1(config-subif)#ip address 10.1.1.1 255.255.255.0

Configuring PPPoE over VLAN

To configure PPPoE over VLAN over a bridged Ethernet interface:
