And what do you do with a BGP customer which sends you traffic from prefixes he doesn't want to announce to you? There are such customers. Fail filter ACL?This has been my question with uRPF from the beginning. You can solve this on for some networks, but it doesn't scale very well. Especially where you really don't know that your customer's customer is doing this.It's 2004, and so, your customers who want to do this have to explain why, and you have to maintain extra-ordinary filters for such customers, at either your cost or the customer's cost.ah-ha! Patriot-Act!
I was reminded that I forgot my ":)" on that post... I was joking, sort of, and NOT attempting to rile the politicos either. Poor choice of time/place on my part.
not nearly. i'm not asking you to take your shoes off before you get on an airplane, nor fingerprinting you before you enter the country, nor secretly searching your residence while you're at work. the closest analogue would be wanting your body to be on the plane if your luggage is, and wanting the name on your ticket to be the same as the name on your photo-id.
Agreed, and some of these things will come with time... As I mentioned earlier on this thread (I think) 'new equipment requirements include line-rate filtering on all interfaces' (vendors mostly have taken this to heart, those that have not should read the former 'jones draft' now RFC 3871 and start doing things better)
