Usage Guidelines
The BVI is a virtual interface within the router that acts like a normal routed interface. The BVI does not
support bridging itself, but acts as a gateway for the corresponding bridge-domain to a routed interface within
the router.
Aside from supporting a configurable MAC address, a BVI supports only Layer 3 attributes, and has the
following characteristics:
• Uses a MAC address taken from the local chassis MAC address pool, unless overridden at the BVI
• Is configured as an interface type using the interface bvi command and uses an IPv4 or IPv6 address
