VLAN overview
FIGURE 40 Use virtual routing interfaces for routing between Layer 3 protocol VLANs
VLAN and virtual routing interface groups
Devices support the configuration of VLAN groups. To simplify configuration, you can configure
VLAN groups and virtual routing interface groups. When you create a VLAN group, the VLAN
parameters you configure for the group apply to all the VLANs within the group. Additionally, you
can easily associate the same IP subnet interface with all the VLANs in a group by configuring a
virtual routing interface group with the same ID as the VLAN group.
For configuration information, refer to “Configuring VLAN groups and virtual routing interface
groups” on page 395.

Layer 2 and Layer 3 traffic within a VLAN
is bridged at Layer 2.
Layer 3 traffic between protocol VLANs
is routed using virtual interfaces (VE).
To route to one another, each protocol
VLAN must have a virtual interface.
