Well, yes, that goes hand-in-hand with "...expects hefty charge". To me, this just says T-Mobile wants out of the POTS business at almost any cost. All those poor people stuck with Cogent now, I feel sorry for them! Adam Thompson Consultant, Infrastructure Services MERLIN 100 - 135

NANOG 86 - Hotel Group Rate

The group rate of $250 USD/night is full and no longer available. Online availability is $355 USD/night. But if you call, wait on hold, and ask for the AAA discount, the rate is $305 USD/night. Thought I would share as it may help others save a little money. AK

RE: BCP38 For BGP Customers

We’ve seen Juniper EX9ks implement uRPF in such a way that if I have two (load-balanced) BGP connections to the EX9k, and uRPF is turned on facing me, I immediately experience ~50% outbound packet loss. Methinks the EX9ks apply uRPF a little too close to the hardware and ignore the RIB. -Adam

RE: Can I do this in EVPN? (Multihome to more different CEs)

e too much money and need to use some up. Cisco vPC does essentially the same thing, as does Juniper's VC. Extreme has something similar, too. STP does not get transported across the VXLAN transport, so you now avoid all the inherent problems with long-distance or multi-site STP bridgin

RE: 10G CPE w/VXLAN - vendors?

wed from the IaaS perspective, this is a bunch of DC-DC connections… but relative to the overall network, the customer-prem devices fall into the traditional “CPE” category. (Most customers either just plug in bare fiber, or they connect to an intermediate carrier’s CPE.) Adam Thompson Consult
