OSPF Status
T ransit Delay—The es timated number of seconds it tak es to transmit a link - state update pack et ov er this
interface.
Interfa ce R etra nsm it In ter val—The number of seconds between the link-state advertisement
retransmi ssions, f o r adj ace nc ies belo ngi ng to th is int erf ac e. This value is also used wh en re tr an smitt ing
database description and link-state request packets.
Hello Interval—The time interval, in seconds, between th e Hello pa ckets that the router sends on th e
interface. This value must be the same for all the routers attached to a common network.
Router Dead interval—The time interval, in seconds, durin g which a router's Hello packets are not
recei v ed before it's neighb ors declar e the ro uter do wn. T his is a mu ltiple of the Hello inte rv al. Th is val ue
must be the same for all the routers attached to a common network.
Poll Interval—The larger time interval, in seconds, between the Hello packets s ent to an inactive
non-broadcast multi-access neighbor.
Interfa ce Sta t e—The OSPF Interface State.
Design ated Router—The IP Address of the Designated Router.
Backup D esignate d router—The IP Address of th e Backup Designated Router.
Interfa ce Even ts—The number of times this OSPF interface has changed its state, or an erro r has
occurred.

Interf ace Metri c

Addressless Interface—Dif ferentiates the addressless inter faces from the a ddressed inter faces. When the
va lue is set to zero, it signifies that the interface has an IP address.
Interfa ce Me tr ic TOS—Th e type of s ervice me tric be ing refere nced .
Interfa ce Metri c IP Addr ess—The IP address of this OSPF interface.
Metric—T he metric of using this typ e of service on t his interface . The def ault v alue of the T OS 0 Metric
is 10^8 / ifSpeed.
Metric Status—Displays the validity or invalidity of the entry. Setting it to 'invalid' has the effect of
render ing i t inope rat ive.

Virtua l Inter fac e

Vir Interface Neighbor—The Router ID of the Virtua l Neighbo r.
Vir Interface Area ID—The Transit Area that the Virtual Link traverses.
Vir Interface Transit Delay—T he est ima ted nu mber of sec onds it t akes to t ransm it a l ink- sta te updat e
packet over th is interface.
Vir Interface Retransmit Interval—The num ber of seco nds betwe en link-st ate ad vertisem ent
retransmi ssions, f o r adj ace nc ies belo ngi ng to th is int erf ac e. This value is also used wh en re tr an smitt ing
the dat abas e descr ipt ion an d li nk -sta te re que st p ackets. Th is value sh ould be g re ater th an t he expec ted
round-t rip time.
Vir Interface Hello Interval—The time interval, in seconds, between the Hello packets that the router
sends on the inte rface. This value must be the same for the virtu al neighbo r.
V ir Interface Router Dead Interval—The ti me int erv al, i n seco nds, during whic h a rou ter's H ello pack ets
are no t received before it's neighbors declare the router down. This is a multiple of the Hello interval.
This value m ust b e the same for t he v irt ual ne ighb or.
Vir Interface State—Signifies the OSPF virtual interface states.
