Hi Chris,
The conversation is about "slow router" in transit position.
And as I said, operators do not create artificial choke-points by putting only slow
routers in important/critical/core "transit" positions in the network; this
would be silly network design, operators will not do this, and we do not modify or design
our routing protocols to support silly network designs.
Thanks,
Chris.

Hi All,
Here is an email I would like to address multiple comments and issues.
My comment starts with [lc]

1. About the weakest control plane
From Chris. H
Operators with 1000s of routers and routers with 1000s of interfaces
don't create flooding choke-points, and especially don't then drop
crappy routers in said choke-points. We should not modify our routing
protocols to support such poor network design.
<<<
[lc] For a network of 1000+ routers, it is usually NOT a greenfield
deployment. It is likely a brownfield deployment.
There are reasons that these older generations of routers could not be
replaced easily. One common problem is the legacy interface support,
and the port density of such low speed interfaces.
I did not say that operators have no slow/crappy routers.
Have you heard that some operators still ask for 1G/10G support in new
core router?
Therefore, it requires some method to let these "weaker" control
planes to co-exist, plus rather predictable network stability. I'll
show you how it can be achieved.
No it doesn't, since slow routers on the network edge work just fine w/o
affecting overall stability or flooding speed of the core.
Thanks,
Chris.
