Re: /24 multihoming issue

[Kyaw Khine <joekhine () yahoo com>]

I've heard and seen those filters a few years ago. In
this particular case, I've seen a bunch of other /24s
(from remote ASs) on the looking glasses. 
Looks like filters are base on other criteria on top
of prefix length and I wonder which criterion this /24
falls into.
