OSPFv3 Interface Statistics
This screen displays statistics for the selected interface. The information will be displayed
only if OSPFv3 is enabled.
State (cont.) • Backup Designated Router — This router is
itself the Backup Designated Router on the
attached network. It will be promoted to
Designated Router if the present Designated
Router fails. The router establishes adjacencies
to all other routers attached to the network. The
Backup Designated Router performs slightly
different functions during the LSA flooding
Procedure, as compared to the Designated
Router.
• Other Designated Router — The interface is
connected to a broadcast or NBMA network on
which other routers have been selected to be
either the Designated Router and Backup
Designated Router. The router attempts to form
adjacencies to both the Designated Router and
the Backup Designated Router.
Note: The State is only displayed if the OSPFv3
Admin Mode is enabled.
