Configuring Routing Between VLANs
How to Configure Routing Between VLANS
13
Restrictions
• Each command you enter while you are in interface configuration mode with the interface range
command is executed as it is entered. The commands are not batched together for execution after
you exit interface configuration mode. If you exit interface configuration mode while the commands
are being executed, some commands might not be executed on some interfaces in the range. Wait
until the command prompt reappears before exiting interface configuration mode.
• The no interface range command is not supported. You must delete individual subinterfaces to
delete a range.
Supported Platforms
For Cisco IOS Release 12.2(13)T, the following platforms are supported:
• Cisco 6400 series
• Cisco 7200 series
• Cisco 7401 ASR router
Benefits
The VLAN Range feature provides the following benefits:
Simultaneous Configurations
Identical commands can be entered once for a range of subinterfaces, rather than being entered
separately for each subinterface.
Overlapping Range Configurations
Overlapping ranges of subinterfaces can be configured.
Customized Subinterfaces
Individual subinterfaces within a range can be customized or deleted.
Configuring a Range of VLAN Subinterfaces
Use the following commands to configure a range of VLAN subinterfaces.
