Searching the draft there are actually a lot of “Strict-Mode for BFD” w/o
“OSPF” preceding it.
I agree w Acee’s suggestion – always use “OSPF BFD Strict-Mode”.

Robert –
It is good that you take an active interest in this technology – but I think
the suggestions you are making should not be targeted at IGP use of BFD.
Discussion of how to make BFD failure detection more robust belongs in the BFD
WG – and – as you know – that WG has taken an interest
I strongly support progression of this document.
Equivalent functionality has been defined for IS-IS (RFC 6213) and has proven
very useful.
Although I am aware that some implementations have achieved the benefits of
strict-mode behavior by careful configuration, this suffers from the lack of
o consider
this scale. I am not going to try to convince you otherwise.
But if so you aren’t solving the problem we have been asked to solve.

With 100K PE scale, we are talking about 100K BFD sessions/PE and close to 5
million BFD sessions network-wide.
Eliminating one of the options we are discussing is admittedly a small step,
but still worthwhile.
However, If you still want to continue to advocate for BFD, I will say no
of Tony’s proposal
since he doesn’t think the IGP should be in the business of sending node
liveness information.
The service itself doesn’t even need to be running on a router at all.

I recognize this as an alternative which some might find useful in some

I also understand why and find it appropriate that you have introduced

I believe the most valuable feedback you received during your presentation at
IETF 112 is that using IGPs likely will not meet the deployment requirements.
In particular, persistence of a given client session with a given application
server is likely a requirement which will not be
+1
Hopefully this would help us understand the use cases better and why/if more
than one solution might be appropriate.
Can’t happen too soon IMO.

Given that IGPs provide the ability to advertise summaries (in the interest of
scalability), I think it is reasonable to say that being able to advertise
reachability changes of endpoints covered by the summary also can be considered

This thread is becoming "diverse".
We are trying to talk about many different solutions (IGP, BGP, BFD) - all of
which may be useful and certainly are not mutually exclusive.
If we can agree that an IGP solution is useful, then we can use this thread to
set a direction for the IGP solution -

You continue to confuse Flex and ASLA.
I
ASLA Flex-specific – that would unduly constrain
future applications to be “just-like Flex”.
And, Flex is doing just fine as it is – one of the indicators of which I
believe is your enthusiasm for it.

But the entire point of A-bit is that you are doing this exercise to make sure
implementations to handle the
various combinations of possible deployments (only zero ABM, mix of zero-ABM
and A-bit, all A-bit) I do not see that ROI is worth it.

Comment #1
Regarding the example discussed in the Introduction, let's see if I understand
it correctly.
There are three (possibly more) applications enabled in the network. Let's call
them X, Y, and Z.
There are two attribute types being advertised on a given (set of) link(s).
Ron -
Indeed - it is long past the time when we should be focusing on the "big
picture".
I think Acee has stated it as succinctly as anyone - let me repeat for emphasis:
"The LSR WG developed ASLAs to cover usage of the link attributes (including
metrics) for different applications and
Qin -
Just to note that RFC 5310 does NOT replace or obsolete RFC 5304. Both RFC 's
have their uses.
Please be sure to reference both RFCs in your updated text.
Thanx.

For IS-IS security please also see RFC 5310.
For OSPF security please see RFC 5709.
Regarding the debate about MUST vs SHOULD, as I see it advertisement of this

a given implementation/deployment - and I
