DESCRIPTION
" On an interface having an IP Address, zero. On
addressless interfaces, the corresponding value of
ifIndex in the Internet Standard MIB. On row creation,
this can be derived from the instance."
::= { ospfNbrEntry 2 }
ospfNbrRtrId OBJECT-TYPE
SYNTAX RouterID
ACCESS read-only
STATUS mandatory
DESCRIPTION
"A 32-bit integer (represented as a type IpAddress)
uniquely identifying the neighboring router in the
Autonomous System."
DEFVAL { '00000000'H } -- 0.0.0.0
::= { ospfNbrEntry 3 }
ospfNbrOptions OBJECT-TYPE
SYNTAX INTEGER
ACCESS read-only
STATUS mandatory
DESCRIPTION
"A Bit Mask corresponding to the neighbor's options
field.
Bit 0, if set, indicates that the area accepts and
operates on external information; if zero, it is a stub
area.
Bit 1, if set, indicates that the system will operate
on Type of Service metrics other than TOS 0. If zero,
the neighbor will ignore all metrics except the TOS 0
metric."

"OSPF Version 2, Section 12.1.2 Options"
DEFVAL { 0 }
::= { ospfNbrEntry 4 }
ospfNbrPriority OBJECT-TYPE
SYNTAX DesignatedRouterPriority
ACCESS read-write
STATUS mandatory
DESCRIPTION
"The priority of this neighbor in the designated router
election algorithm. The value 0 signifies that the
neighbor is not eligible to become the designated
router on this particular network."

DESCRIPTION
"The number of times this neighbor relationship has
changed state, or an error has occurred."
DEFVAL { 0 }
::= { ospfNbrEntry 7 }
ospfNbrLSRetransQLen OBJECT-TYPE

ACCESS read-only
STATUS mandatory
DESCRIPTION
"The current length of the retransmission queue."
DEFVAL { 0 }
::= { ospfNbrEntry 8 }
ospfNBMANbrStatus OBJECT-TYPE
SYNTAX Validation
ACCESS read-write
STATUS mandatory
DESCRIPTION
"This variable displays the validity or invalidity of
the entry. Setting it to 'invalid' has the effect of
rendering it inoperative. The internal effect (row
removal) is implementation dependent."
DEFVAL { valid }
::= { ospfNbrEntry 9 }
