The larger story here is...

"7. Routing.  Routers connect T-Mobile’s LTE towers to T-Mobile’s LTE
network.  These routers utilize a routing protocol called Open
Shortest Path First."

you can blow it with is-is, just as you can with ospf, just as you can
with pretty much any dynamic [routing] protocol.  though i am an is-is
fanboy, i would not blame the protocol.  and if they can not manage the
currently deployed protocol, i am not sure i would recommend they try a
delicate transition.

Absolutely all of these guns pointed at toes can be problematic.
I don't often get a chance to poke fun at vijay though :)

On the bright side that write up by TMO was pretty great as a read...
good details  (or more than I expected from telco).
