RFC 5060, "Protocol Independent Multicast MIB", January 2008

Errata ID: 1449

Status: Verified
Type: Technical

Reported By: Alfred Hoenes

Section 5, pg.49 ff. says:

pimSGIJoinPruneState OBJECT-TYPE
    SYNTAX     INTEGER {

    STATUS     current
    DESCRIPTION
            "The state resulting from (S,G) Join/Prune messages

    REFERENCE "RFC 4601 section 4.5.3 and RFC 3973 section 4.4.2"

It should say:

pimSGIJoinPruneState OBJECT-TYPE
    SYNTAX     INTEGER {
                  noInfo (1),
                  join (2),
                  prunePending (3),
                  pruned (4)
               }
    MAX-ACCESS read-only
    STATUS     current
    DESCRIPTION
            "The state resulting from (S,G) Join/Prune messages
            received on this interface.  This corresponds to the state
            of the downstream per-interface (S,G) state machine in the
            PIM-SM and PIM-DM specification."
    REFERENCE "RFC 4601 section 4.5.3 and RFC 3973 section 4.4.2"
    ::= { pimSGIEntry 4 }

Notes:

A fourth state is added to allow for the reporting of pruned state in PIM-DM.

Errata ID: 1445

Section 5, pg.12 says:

pimInvalidRegisterAddressType
    ...
    DESCRIPTION
            "The address type stored in pimInvalidRegisterOrigin,
            pimInvalidRegisterGroup, and pimInvalidRegisterRp.
            [...]

It should say:

pimInvalidRegisterAddressType
    ...
    DESCRIPTION
|           "The type of the addresses stored in
            pimInvalidRegisterOrigin,
            pimInvalidRegisterGroup, and pimInvalidRegisterRp.
            [...]

Notes:

The Original Text is misleading. No "address type [is] stored" in
the columnar objects pimInvalidRegisterOrigin,
pimInvalidRegisterGroup, and pimInvalidRegisterRp; addresses are!
The addres type for these addresses is stored in
pimInvalidRegisterAddressType -- as its name says.

Section 5, pg.20 says:

pimInterfaceTrigHelloInterval
    ...
    DESCRIPTION
       ...

It should say:

       the 'Triggered_Hello_Delay' timer ...

Notes:

Typo yields invalid variable name / reference to the PIM-SM spec.

Errata ID: 1447

Rejected by: Adrian Farrel
Date Rejected: 2011-09-28

Section 5, pg.32 ff. says:


Notes:

The description clauses of many columnar objects in the
PIM (*,G) State Table are underspecified:
If an object is "used with" a specific variant of PIM,
what is the desired behavior for other variants?
- shall the object be instantiated or not?
- if yes, what's the default / substitute value in this case?
- shouldn't such defaults be listed in DEFAULT clauses ?

Similar deficiencies also exist in the descriptions of objects
in other MIB tables in this MIB module.
--VERIFIER NOTES--
I don't see this as underspecified at all. In fact, objects like pimSGPimMode
and pimStaticRPPimMode are very specific in only supporting a limited range of
modes for the entire table. In effect, if another mode is in use, the table
cannot be used by definition.

Errata ID: 1448

Section 5, pg.47/48 says:

pimSGUpstreamPruneState OBJECT-TYPE
    SYNTAX     INTEGER {
 |                forwarding (1),
                  ackpending (2),
                  pruned (3)
               }
    ...
    DESCRIPTION
            "Whether the local router has pruned itself from the tree.
            This corresponds to the state of the upstream prune (S,G)
|           state machine in the PIM-DM specification.  This object is
|           used only by PIM-DM."

Notes:

The DESCRIPTION clause says: "This object is used only by PIM-DM."
Does this mean: "This object is only instantiated for PIM-DM." ?
Otherwise, the alternative:
noinfo(0),
should perhaps be allowed in the SYNTAX clause and be the DEFAULT.

Similar issues exist for the subsequent columnar objects,
pimSGUpstreamPruneLimitTimer, pimSGOriginatorState,
pimSGSourceActiveTimer, and pimSGStateRefreshTimer.

Also, there's no hint in the RFC why the other applicable
timers, GraftRetryTimer and OverrideTimer have not been
modeled in this MIB module.
--VERIFIER NOTES--
There are two issues in this Erratum...

1. "This object is only used..."

I interpret this to mean that an attempt to read the object in
other cases would return an error. Thus I don't see a problem
with the current text, and reject this part of the Erratum

2. "other timers are not modelled" Specifically:

GraftRetryTimer - I see pimInterfaceGraftRetryInterval
OverrideTimer - I see pimInterfaceOverrideInterval

The question is: why can't I see how the timer is running?
This looks like function that could have been added to the
MIB module, but was not.

However, someone who wants this function can add if they
feel inspired by revising the module or writing a new one.
