AreaId
The  Transit  Area  that  the   Virtual   Link

traverses.  By definition, this is not 0.0.0.0
Neighbor
The Router ID of the Virtual Neighbor.
TransitDelay
The estimated number of seconds  it  takes  to

transmit  a link- state update packet over this

interface.
RetransInterval
The number of seconds between  link-state  ad-

vertisement  retransmissions,  for  adjacencies

belonging to this  interface.   This  value  is

also used when retransmitting database descrip-

tion  and  link-state  request  packets.   This

value  should  be well over the expected round-

trip time.
HelloInterval
The length of time, in  seconds,  between  the

Hello  packets that the router sends on the in-

terface.  This value must be the same  for  the

virtual neighbor.
RtrDeadInterval
The number of seconds that  a  router's  Hello

packets  have  not been seen before it's neigh-

bors declare the router down.  This  should  be

some  multiple  of  the  Hello  interval.  This

value must be the same for the  virtual  neigh-

bor.
State
OSPF virtual interface states.
Enumerations:
  • down (1)
  • pointToPoint (4)
Events
The number of state changes or error events on

this Virtual Link
AuthKey
If Authentication Type is simplePassword,  the

device  will left adjust and zero fill to 8 oc-

tets.

Note that unauthenticated  interfaces  need  no

authentication key, and simple password authen-

tication cannot use a key of more  than  8  oc-

tets.  Larger keys are useful only with authen-

tication mechanisms not specified in this docu-

ment.

When  read,  ospfVirtIfAuthKey  always  returns  a

string of length zero.
Status
This variable displays the status of  the  en-

try.  Setting it to 'invalid' has the effect of

rendering it inoperative.  The internal  effect

(row removal) is implementation dependent.
Enumerations:
  • valid (1)
  • invalid (2)
AuthType
The authentication type specified for a virtu-

al  interface.  Additional authentication types

may be assigned locally.
