Configuring Routing 479
– Backup Designated Router — This router is the Backup Designated Router on the attached
network. It is 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 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 the Designated Router and Backup Designated
Router either. The router attempts to form adjacencies to both the Designated Router and the
Backup Designated Router.
• Designated Router — The identity of the Designated Router for this network, in the view of the
advertising router. The Designated Router is identified here by its router ID. The value 0.0.0.0 means
that there is no Designated Router. This field is only displayed if the OSPF admin mode is enabled.
• Backup Designated Router — The identity of the Backup Designated Router for this network, in the
view of the advertising router. The Backup Designated Router is identified here by its router ID. Set to
0.0.0.0 if there is no Backup Designated Router. This field is only displayed if the OSPF admin mode is
enabled.
• Number of Link Events — This is the number of times the specified OSPF interface has changed its
state. This field is only displayed if the OSPF admin mode is enabled.
• Local Link LSAs — The number of opaque LSAs whose flooding scope is the link on this interface.
• Local Link LSA Checksum — The sum of the checksums of local link LSAs for this link.
•
Metric Cost — Enter the value on this interface for the cost TOS (type of service). The range for the
metric cost is between 1 and 65,535. Metric Cost is only configurable/displayed if OSPF is initialized
on the interface.
