Variable Value
• backupDesignatedRouter
• otherDesignatedRouter
DesignatedRouter A read-only field indicating the router ID of the designated
router.
BackupDesignatedRouter A read-only field indicating the router ID of the backup
designated router.
Events A read-only field indicating the number of times this OSPF
interface changed state or an error occurred.
MetricValue The metric assigned to this interface. The default value of
the metric is the reference bandwidth or ifSpeed. The value
of the reference bandwidth is configured by the
rcOspfv3ReferenceBandwidth object.
LinkScopeLsaCount A read-only field indicating the number of Link-Scope link-
state advertisements in the link-state database.
LinkLsaChksumSum A read-only field indicating the 32-bit unsigned sum of the
Link-Scope link-state advertisement LS checksums in the
link-state database. The sum determines a change in the
router link-state database and compares the link-state
database of two routers.
InstId Enables multiple instances of OSPFv3 over a single link.
The switch assigns each protocol instance a separate ID.
This ID is significant for local links only. The default is 0.
Adding NBMA neighbors
In contrast to a broadcast network where switches multicast (send to AllSPFRouters and
AllDRouters) certain OSPF protocol packets, switches replicate and send NBMA packets to
each neighboring router as unicast. NBMA networks drop all OSPF packets with destination
addresses AllSPFRouters and AllDRouters. Because the NBMA network does not broadcast,
you must manually configure a list of neighbors and priorities for all routers in the network that
can become the designated router (DR). Potential DRs use a positive nonzero router priority.
An NMBA interface with a positive nonzero router priority is eligible to become the DR for the
NBMA network and is configured with the identification of all attached routers, IPv6 addresses,
and router priorities.
