Pitfalls of annoucing /24s

Wed Oct 15 22:11:07 UTC 2003

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.

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.
