It's related to your hold timer and your convergence time. Lower to 14/45s
and it will be much faster.

Trey,
That is the main question. If it takes the rest of the Internet 10 mins to
figure out my BGP dropped, does it matter if I spend $ of some super fast
router that can build the tables in 30s?

Lower timers to 15s/45s and see if you can enable BFD, I think this has to
be coordinated with the upstreams? maybe someone can confirm

You can prevent this by having a backup default route. The other thing
is if you are n a physical interface or aggregated interface with a vlan
on your upstream's router. If its physical it should stop routing
traffic when it sees the interface down. If not it may keep trying to
send traffic

Some OTDRs have these filters built in when you are testing on 1650.

Oh I 100% believe they could do it. If I knew tx power of the OTDR it would be
easy to estimate how close they’d have to be to exceed the overload threshold
of the transceiver.
“Dynamic Range” has to be a diff between Tx and sensitivity …..or so I would
assume. If it is then I could guess

We have a Juniper MX10008 which is supposed to crunch a full table in about
30 seconds, but that's a half million dollar router.
If you're doing it on a general purpose CPU I think 10-15 minutes doesn't
sound weird.
Something I've been meaning to try in the lab was having a static default

Does anyone know how strong the pulses from an OTDR might be? Is there a
rule of thumb to guess that based on the dynamic range?
I'm trying to determine if a dark fiber provider might have blasted a ZR

We have two circuits coming into our NOC. We peer with 3 different providers
on each circuit. If a circuit fails, BGP will do it's magic and traffic will
