Sorry for the misfire on my last email. The 206.81.80.0/23 network is assigned to the SIX from ARIN. In general, we don't want people to announce that space to the DFZ, so the three providers listed above are not filtering their announcements properly. It is, as others have said, a good idea to announce the exchange block to your customers, but not out to the DFZ.
why is it a good idea to send this to your customers? the next-hop info is surely only useful to your local network? done right it's even only relevant to the IX connected router, right? it seems wholely unusful to your customers. (to me at least)
I was thinking about what Leo said about tools that test each hop through a path. At least my downstream customers will be able to test through the SIX connection if I announce the /23 to them. Mike
