Hi,
I have one query related to OSPFv3 MIB (rfc5643)
For the below field the range is defined from 1 to 1800
Ospfv3UpToRefreshIntervalTC
SYNTAX Unsigned32 (1..1800)
And below is one of the many entries that are using this Syntax
ospfv3NbrRestartHelperAge OBJECT-TYPE
SYNTAX Ospfv3UpToRefreshIntervalTC
UNITS "seconds"
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"Remaining time in current OSPF Graceful restart
interval, if the router is acting as a restart
helper for the neighbor."
::= { ospfv3NbrEntry 14 }
So now If Process is not HELPER enabled, and Current state of Helper is
NONE.
So what value must be displayed for "ospfv3NbrRestartHelperAge" ?
Value 0 can not be displayed as it is not in range.
This problem does not exist in OSPFv2, as no such range is specified
Similar issues are present in other table entires too where the minimum
value is 1 instead of 0.
For eg:
ospfv3NbrIfId OBJECT-TYPE
SYNTAX InterfaceIndex
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The interface ID that the neighbor advertises
in its Hello Packets on this link, that is, the
neighbor's local interface index."
::= { ospfv3NbrEntry 12 }
Here InterfaceIndex range start from 1
But in case of NBMA nbr which is created due to configuration, this field
will be 0. So how to display this field ?
Other similar fields are ROUTER-Id, [Interface DR/BDR values refer to Router
id, and for P2P interface how to display value 0 ]
Thanks and regards
Abhishek
