Greetings,
I'm curious to get some input from everyone about Verizons TLS service.
What do you think of it? What kind of hardware do you use at your edge
and at the CPE. Example configs?
We have a GigE connection at the core and order 100M circuits with
whatever size EVC we require for the customer. I use rate limiting on
the customers ethernet interface. A basic /30 serial between us and
them and a static route in both directions.
I have seen some strange things happen. This is a forklift upgrade for
one customer that's going from 2 T1s to 10M TLS. When I had them
connect our TLS router to their public switch things went nuts on the VZ
side of the circuit (2500PPS) and stayed at around 100PPS on the
customer side. This doesn't make much sense to me considering the T1
router has no problems and it's not like we're connecting a switch on
our side to a switch on their side and causing a loop somewhere, there's
a router at both ends. I originally suspected VZ as the problem but
eliminated that idea by connecting a laptop directly to the customer
hand off. The core router is a Cisco 7206VXR and the CPE is a 2651XM.
When he connected a switch with no VLANs on it things quieted down a
bit. It's pretty obvious his switch is causing a problem but why it has
issues with the TLS and not the T1s is beyond me.
Here's a quick diagram:

Any input would be greatly appreciated.
