Configuring A Virtual Routing Interface Group - HP ProCurve 9304M Installation And Configuration Manual

NOTE: The device's memory must be configured to contain at least the number of VLANs you specify for the
higher end of the range. For example, if you specify 2048 as the VLAN ID at the high end of the range, you first
must increase the memory allocation for VLANs to 2048 or higher. Additionally, on Routing Switches, if you
allocate additional memory for VLANs, you also need to allocate the same amount of memory for virtual routing
interfaces, before you configure the VLAN groups. This is true regardless of whether you use the virtual routing
interface groups. The memory allocation is required because the VLAN groups and virtual routing interface
groups have a one-to-one mapping. See "Allocating Memory for More VLANs or Virtual Routing Interfaces" on
page 11-41.
If a VLAN within the range you specify is already configured, the CLI does not add the group but instead displays
an error message. In this case, create the group by specifying a valid contiguous range. Then add more VLANs
to the group after the CLI changes to the configuration level for the group. See the following example.
You can add and remove individual VLANs or VLAN ranges from at the VLAN group configuration level. For
example, if you want to add VLANs 1001 and 1002 to VLAN group 1 and remove VLANs 900 through 1000, enter
the following commands:
HP9300(config-vlan-group-1)# add-vlan 1001 to 1002
HP9300(config-vlan-group-1)# remove-vlan 900 to 1000
Syntax: add-vlan <vlan-id> [to <vlan-id>]
Syntax: remove-vlan <vlan-id> [to <vlan-id>]
USING THE WEB MANAGEMENT INTERFACE
You cannot configure this feature using the Web management interface.
Displaying Information about VLAN Groups
To display VLAN group configuration information, enter the following command:
HP9300# show vlan-group
vlan-group 1 vlan 2 to 20
tagged ethe 1/1 to 1/2
!
vlan-group 2 vlan 21 to 40
tagged ethe 1/1 to 1/2
!
Syntax: show vlan-group [<group-id>]
This example shows configuration information for two VLAN groups, group 1 and group 2.
The <group-id> specifies a VLAN group. If you do not use this parameter, the configuration information for all the
configured VLAN groups is displayed.

Configuring a Virtual Routing Interface Group

A virtual routing interface group allows you to associate the same IP sub-net interface with multiple port-based
VLANs. For example, if you associate a virtual routing interface group with a VLAN group, all the VLANs in the
group have the IP interface of the virtual routing interface group.
To configure a virtual routing interface group, use the following CLI method.
NOTE: When you configure a virtual routing interface group, all members of the group have the same IP sub-net
address. This feature is useful in collocation environments where the device has many IP addresses and you
want to conserve the IP address space.
USING THE CLI
To configure a virtual routing interface group, enter commands such as the following:
HP9300(config)# vlan-group 1
HP9300(config-vlan-group-1)# group-router-interface
