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
interface.
•
Is configured as an interface type using the interface bvi command and uses an IPv4 or IPv6 address
that is in the same subnet as the hosts on the segments of the bridged domain. The BVI also supports
secondary addresses.
•
The BVI identifier is independent of the bridge-domain identifier. These identifiers do not need to
correlate like they do in Cisco IOS software.
•
Is associated to a bridge group using the routed interface bvi command.
•
The following interface commands are supported on a BVI:
•
arp purge-delay
•
arp timeout
•
bandwidth (The default is 10 Gbps and is used as the cost metric for routing protocols for the
BVI.)
