VLAN routing

A VLAN restricts the broadcast domain to only its interface members. If nodes connected to two
different VLANs want to communicate, they require an external router to route between the VLANs.
Optionally, Brocade DCB products offer the ability to create a Switch Virtual Interface (SVI) to route
between VLANs.
An SVI is a VLAN of switch ports represented by one interface to a routing or bridging system. There
is no physical interface for the VLAN and the SVI provides the Layer 3 processing for packets from
all switch ports associated with the VLAN. There is one-to-one mapping between a VLAN and an
SVI; therefore, only a single SVI can be mapped to a VLAN. The VLAN is mapped to a network
address using the SVI. All the nodes in the VLAN will belong to the subnet of the SVI.
NOTE
In IOS terms, an SVI is also called a Virtual Routing Interface (VRI). The SVI in DCB products and VRI
in IOS products are the same.
