Hello, route filters?

I guess I see the rationale behind passing this cruft along to EXDS
transit customers who haven't yet read the filtering section of Halabi
(remember: more specifics == more outbound traffic from customer ==
more revenue). But exchange points?

Just a brief follow-up to what I posted previously...

I guess I see the rationale behind passing this cruft along to EXDS
transit customers who haven't yet read the filtering section of
Halabi (remember: more specifics == more outbound traffic from
customer == more revenue). But exchange points?

This is a full view from Exodus:

x.x.x.x 4 3967 243954 11543 752069 0 0 1d11h 106124

This is the same full view from Exodus if they'd practice what they
preach(ed) and apply <http://www.nielsen.net/people/christian/linx.html&gt;:

x.x.x.x 4 3967 262248 11546 752112 26 0 1d11h 87853

There are some particularly entertaining "bogons" (well, in my mind)
in the non-abbreviated version, including:

$ /usr/local/rancid/bin/clogin -c "show ip bgp regex 3967_" border1.nyc1 > exds-routes
$ grep "/32" exds-routes |wc -l
     27
$ grep "/31" exds-routes | wc -l
      2
$ grep "/30" exds-routes | wc -l
    293
$ grep "/29" exds-routes | wc -l
    114
$ grep "/28" exds-routes | wc -l
    269
$ grep "/27" exds-routes | wc -l
    220
$ grep "/26" exds-routes | wc -l
    275
$ grep "/25" exds-routes | wc -l
    312
$ grep "> 10." exds-routes
*> 10.255.253.34/32 x.x.x.x 0 3967 i
*> 10.255.253.35/32 x.x.x.x 0 3967 i
*> 10.255.254.34/32 x.x.x.x 0 3967 i
*> 10.255.254.35/32 x.x.x.x 0 3967 i

Can a brother get some prefix-filters?

if you were my neighbor, and you had a gangly tree overgrown into my
yard that i took an issue to, i think i would most likely call or talk to
you personally about the issue, rather than carry out some agenda by
sending pictures of it to the community newsletter, saying "hey everyone
look what this guy is doing"

Or just cut the branches that were on my property (i.e. filter incoming).

as has been said in the past... this is being addressed. getting
customers to renumber is, well, not a trivial task.

There is a difference between getting customers to renumber and announcing
/27s and longer to all and sundry.

The issue is being addressed and will be going away.
