Configuring Static VLAN Subinterfaces Within VLAN Subranges
Copyright © 2010, Juniper Networks, Inc.
Use to administratively disable (shut down) a specified VLAN subrange or all subranges
in a VLAN range. The administrative state of a VLAN subrange is enabled by default.
Disabling the VLAN subrange deletes all dynamic VLAN subinterfaces on the affected
subranges. You can use the show vlan subinterface command to monitor the progress
of the removal of all dynamic VLAN subinterfaces for the specified subrange.
No dynamic VLAN subinterfaces can subsequently be created for the subrange until
you restore the administrative state to enabled by using the no vlan bulk-config
shutdown command.
Example
host1(config-if)#vlan bulk-config test shutdown svlan-range 200 250 1 3
Use the no version to enable the specified VLAN subrange or all subranges in a VLAN
range.
See vlan bulk-config shutdown.
You can do either of the following on an E Series router:
Create a static VLAN subinterface within an existing bulk-configured VLAN subrange
Create a bulk-configured VLAN subrange that includes an existing static VLAN
subinterface
The following sections describe how to perform these tasks.
The example procedures in this section show how to configure static VLAN subinterfaces
within VLAN subranges by using the same loopback interface referenced by multiple
unnumbered IP interfaces. Instead of assigning a different IP address to each physical
interface, the first example assigns an IP address to a loopback interface (loopback 0).
Each physical interface is then configured as an unnumbered IP interface, referencing
the same loopback interface.
Creating Static VLAN Subinterfaces Within VLAN Subranges
You can configure a static VLAN subinterface with a VLAN whose VLAN ID falls within
an existing bulk-configured VLAN subrange.
To create a static VLAN subinterface within a VLAN subrange:
Create the VLAN major interface.
1.
host1(config)#interface gigabitEthernet 0/0
host1(config-if)#encapsulation vlan
Create a bulk-configured VLAN range that includes one or more VLAN subranges.
2.
host1(config-if)#vlan bulk-config test vlan-range 200 250
Create a static VLAN subinterface by adding a subinterface number to the interface
3.
identification command.
host1(config-if)#interface gigabitEthernet 0/0.2100
