Anyone here from Verizon keeping tabs on FiOS v6?
Maintenance outage last night, PD woke up shortly afterward and collected a /56, no joy after that -- egress traffic gets where it's going, ingress is dropped not far into 701. Only visible covering route is the 2600:4000::/24 aggregate, both externally and via Verizon's looking glass. It looks like there are several reports of the same issue in other areas over the last couple months, where those that work have covering /36s advertised externally and the broken ones don't, e.g. no 2600:4041:2000::/36 here. Happy to follow up off-list, if so inclined. Thanks! -Rob

They're returning fake ICMP echo replies from their BNGs for echo packets with TTL=1, thus any ICMP traceroute (Windows and mtr by default, etc.) seems to terminate at their layer 3 edge. UDP/TCP traceroute are unaffected, ICMP works fine if you set the initial TTL to n+1 where n is the hop that's lying. Support claims that it was a mistake, but it's also been 15+ months and it's pretty deliberate behavior. Draw your own conclusions... -Rob

Re: What's the point of prepend communities?
On Thu, 26 Oct 2017, Jason Lixfeld wrote: Absolutely. I understand the "Prepend to Network blah” use case. The case I don’t get is where the ISP makes no distinction in their policy document about how the prepending of their own AS is applied to their upstream announcements, implying that it’s announced to everyone. The "prepend to everybody" communities are usually implemented as "prepend to all peers", excluding customers, and for some variable definition of "all". YMMV, caveat emptor, et cetera -- in most cases you'll need to experiment. I've used "prepend to all peers" communities a few times to avoid saturating transit links that are being consolidated but still under contract, in order to keep the link viable and in use by the immediate neighbor and their customers, but otherwise make it less attractive to the rest of the world under normal conditions. -Rob
