Hi Alvaro,

Happy New Year !!!

Singapore.

Well .. in Singapore and during most of list discussions dynamic flooding
proposal was not on the table. Now it is.

To me this is game changer and any conclusions reached previously IMHO
should now be revisited.

As far as outcome of the BOF - I am not sure how the conclusion was derived
that we need new protocols - especially only those presented. In real
practical cases a lot of DC clusters are build with at most few hundreds of
L3 nodes which in all flavors of current link state implementations will
work just fine as is.

For MSDCs use of either eBGP or Open/R is deployed.

Now dynamic flooding can extend link state to scale much larger.

Personally IMHO this case is solved. Maybe time to move on to other areas ?
:)

Best,
R.
