Re: Routing Policy and http://rs.arin.net/ip-allocation.html

The owner of the block should be announcing the /16 It should not be chopped up into a whole slew of /24's. It's not sprints fault. I would contact iSTAR. If their customers are multihomed out of that space, and (ex:) came to us, we would accept and announce that space, but not everyone would accept it (such as sprint, and others). If the person in that /24 is not connected to iSTAR, they should have given the address space back already. More folks should probally be filtering this: border1.aa#sh ip b 206.116.0.0 255.255.0.0 longer-prefixes BGP table version is 1776141, local router ID is 131.103.0.35 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal Origin codes: i - IGP, e - EGP, ?

For the first time we have had to deal with Sprint's routing policy as defined by http://www.sprint.net/filter.htm. Here is the situation.

One of our dialup customers wants to access his website in the 206.116.31.0/24 network at another provider. PSI is advertising it as a /24. According to Sprint's routing policy, they do not honour anything longer than a /19 in 206.0.0.0/8 .

I am now in the position trying to explain to the very non-technical customer, why he cant reach that site, which from his point of view just seems like I am passing the buck...

Anyways, my question is, are their any other ISPs/NSPs that follow the same guidelines. UUNet seems to honor it just fine, as does MCI. Is Sprint more hardnosed than most ?
