Section 4.3.1/6.1.1 says:
The Generation_Identifier (GenID) Option SHOULD be included in all Hello messages. The GenID option contains a randomly generated 32-bit value that is regenerated each time PIM forwarding is started or restarted on the interface, including when the router itself restarts. When a Hello message with a new GenID is received from a neighbor, any old Hello information about that neighbor SHOULD be discarded and superseded by the information from the new Hello message. This may cause a new DR to be chosen on that interface.
Notes:
Section 6.1.1, item 2 only considers the possibility of falsified Designated Router election results, it does not consider state thrash due to falsified Hello messages with new Generation_Identifier Options.

Section 4.3.1 says:
Before an interface goes down or changes primary IP address, a Hello message with a zero HoldTime should be sent immediately (with the old IP address if the IP address changed). This will cause PIM neighbors to remove this neighbor (or its old IP address) immediately. After an interface has changed its IP address, it MUST send a Hello message with its new IP address. If an interface changes one of its secondary IP addresses, a Hello message with an updated Address_List option and a non-zero HoldTime should be sent immediately. This will cause PIM neighbors to update this neighbor's list of secondary addresses immediately.
Notes:
Section 6.1.1, item 2 only considers the possibility of falsified Designated Router election results, it does not consider forged Hello messages with zero HoldTime or with altered Address_List options.

Notes:
In state Join, when event “Receive Prune (*,*,RP)” occurs and also in state Prune Pending, when event “Expiry Timer Expires” occurs, a situation occurs where an interface will be pruned possibly more rapidly than expected as in J state, when prune is received, PP state is entered and Prune-pending timer is started, but Expiry timer is not reset/halted/etc and this does have an effect in PP state. This issue is not handled in the detailed description on page 48. Is this intentional?

Section 4.5.1 says:
The action "Send PruneEcho(*,*,RP)" is triggered when the
router stops forwarding on an interface as a result of a
prune. A PruneEcho(*,*,RP) is simply a Prune(*,*,RP) message
sent by the upstream router on a LAN with its own address in
the Upstream Neighbor Address field. Its purpose is to add
additional reliability so that if a Prune that should have
been overridden by another router is lost locally on the LAN,
then the PruneEcho may be received and cause the override to
happen. A PruneEcho(*,*,RP) need not be sent on an interface
that contains only a single PIM neighbor during the time this
state machine was in Prune-Pending state.
Notes:
Forged PruneEcho messages could operate as a form of Denial-of-Service (effectively the same as a Prune(*,*,RP) in this context). The issue is resolved by using AH, but it is not listed as one of the forged message types in section 6.1.1.

Section 4.5.4 says:
Prune-Pending (PP)
The router has received a Prune(S,G,rpt) on this interface
from a downstream neighbor and is waiting to see whether the
prune will be overridden by another downstream router. For
forwarding purposes, the Prune-Pending state functions exactly
like the NoInfo state.
Notes:
If a single Prune(S,G,rpt) stops forwarding, then traffic can be interrupted even when it is still needed. There is a random delay between 0 and Effective_Override_Interval(I) (0 – 2.5 seconds by specification defaults) in which traffic stops until it is overridden and traffic starts flowing again. This appears to be an optimization for efficiency vs. reliability. I believe that this should be noted and made into an optional optimization.

Section 4.9.2 says:
Holdtime is the amount of time a receiver must keep the neighbor
reachable, in seconds. If the Holdtime is set to '0xffff', the
receiver of this message never times out the neighbor. This may be
used with dial-on-demand links, to avoid keeping the link up with
periodic Hello messages.
Notes:
Holdtime is tunable by the sender and is required to be kept by the receiver. This coupled with the “infinity” metric 0xffff produces the conditions necessary for a Denial of Service to be possible. This is not addressed in section 6.1.1 (Forged Link-Local Messages) or 6.4 (Denial-of-Service Attacks). Additionally, utilizing AH will not solve this issue as Hello messages instantiate state upon receipt and this state constitutes the “service” that is abused in this form of attack. A tunable option to accept a maximum Holdtime for security purposes would resolve this condition.

Sections 6.4 and A.2
The rationale for this is that there is no way in PIM-SM to prune traffic off the (*,*,RP) tree, except by Joining the (*,G) tree and then pruning each source individually.
Notes:
The paragraph beginning “The rationale for this…” describes a condition where a small cause can have a great effect – a (*,*,RP) join could cause state that, if it is not needed, requires a (*,G) join and many prunes for each source. This is mentioned as the last point in section 6.4, but section 6.4 fails to mention that “undoing” this state requires a join followed by multiple prunes.

Notes:
PIM state begins with a join for a group sent towards the RP. It is not readily evident that the BSR keeps a list of current RPs for use in the hash function to map groups onto these RPs in order to seed our state.

Section 4.5.4 says:
Receive Prune(S,G,rpt)
The compound Join/Prune message contains a Prune(S,G,rpt).
The (S,G,rpt) downstream state machine on interface I
transitions back to the Prune-Pending state. The Expiry Timer
(ET) is restarted, set to maximum of its current value and the
HoldTime from the triggering Join/Prune message.
It should say:
None suggested.
Notes:
Infinite toggle for every pair of routers where one wants (*,G) and the other wants (*,G) and (S,G,rpt). State moves from Prune -> PruneTmp -> NI -> Prune for the (S,G,rpt) state machine. This causes upstream thrash with Join(S,G,rpt) followed by Prune(S,G,rpt) in continual succession. Which causes Prune (S,G,rpt) state to be state limited to never actually enter Prune state (NI -> PP -> NI).

bool JoinDesired(*,G) {
if (immediate_olist(*,G) != NULL OR
(JoinDesired(*,*,RP(G)) AND
AssertWinner(*, G, RPF_interface(RP(G))) != NULL))
return TRUE
else
return FALSE
}
JoinDesired(*,G) is true when the router has forwarding state that
would cause it to forward traffic for G using shared tree state.
Note that although JoinDesired is true, the router's sending of a
Join(*,G) message may be suppressed by another router sending a
Join(*,G) onto the upstream interface.
Notes:
When would immediate_olist(*,G) be NULL and forwarding state exist?

Section 4.5.7 says:
RPF'(*,G) changes not due to an Assert
An event occurred that caused the next hop towards the RP for
G to change. This may be caused by a change in the MRIB
routing database or the group-to-RP mapping. Note that this
transition does not occur if an Assert is active and the
upstream interface does not change.
The upstream (*,G) state machine remains in Joined state.
Send Join(*,G) to the new upstream neighbor, which is the new
value of RPF'(*,G). Send Prune(*,G) to the old upstream
neighbor, which is the old value of RPF'(*,G). Use the new
value of RP(G) in the Prune(*,G) message or all zeros if RP(G)
becomes unknown (old value of RP(G) may be used instead to
improve behavior in routers implementing older versions of
this spec). Set the Join Timer (JT) to expire after
t_periodic seconds.
Notes:
Sending the Prune(*,G) may help state issues, but if the change in MRIB was spurious or there was a situation where a difference of opinion in lower route costs exists, some traffic may be dropped until the MRIB becomes consistent again.

It would make the Join Timer clearer to understand if an explicit statement was made indicating that if the Join Timer is less than t_override, it should be left unchanged. This needs to be made for “See Prune(S,G) to RPF’(S,G)”, “See Prune(S,G,rpt) to RPF’(S,G)”, and “See Prune(*,G) to RPF’(S,G)”.

Section 4.6.1 says:
An (S,G) data packet arrives on interface I, AND
CouldAssert(S,G,I)==TRUE
An (S,G) data packet arrived on an downstream interface that
is in our (S,G) outgoing interface list. We optimistically
assume that we will be the assert winner for this (S,G), and
so we transition to the "I am Assert Winner" state and perform
Actions A1 (below), which will initiate the assert negotiation
for (S,G).

Notes:
The locations of the definitions of functions are not given. Given that there are so many functions, it would be useful to have a notation that indicates this. I propose adding a “*” next to the page reference that contains the definition of that function as well as adding an explanatory note to the index, such as:

Notes:
In NoInfo state and in the Prune Pending state, upon receipt of the “Receive Prune(*,G)” event, there is an explicit state transition back to its own state. These seem redundant.

Per RFC 3232, RFC 1700 is replaced by an online database. A reference is no longer appropriate.

It should say:
# or Assert(*,G) message to be sent out iif.
Notes:
“should be sent out interface iif” is redundant as “iif” stands for “incoming interface” and this expands to: “should be sent out interface incoming interface”, which is redundant.
--VERIFIER NOTES--
In this case "iif" is the identifier of an interface. It reads better as it is.
