Even if they understand it, why should they accept it? If an ISP assigns an address block, runs BGP with the customer, promotes multi-homing, shouldn't they make a reasonable effort to make it work? Unless I am missing something, I am having a big problem with an ISP assigning a /24 to a multi-homed customer and not accepting /24 routes. -----Original Message----- From: owner-nanog@merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of William Caban Sent: Wednesday, October 15, 2003 5:44 PM To: Jean-Christophe Smith Cc: NANOG Subject: RE: Pitfalls of annoucing /24s I will say most probably yes. I have seen this "problem"(?) on many small business customers. The hard part is trying to explain that to them. -William On Wed, 2003-10-15 at 17:16, Jean-Christophe Smith wrote:

I noticed the verio filter policy, in relation to inbound: - In the traditional Class A space (i.e., 0/1), we accept /22 and shorter.

If I want to announce a /24 in the 64.x.x.x space(traditional Class A space) am I'm going to have a problem with other networks that have peer filters similar to Verios?
