Re: ISP Policies
- From: Peter Wohlers

Once upon a career, I was involved with shipping cargo via ocean vessel
to Kuwait (and other Arab countries). We had to provide signed
affadavits from the ships owners that the carrying vessels were neither
Israeli owned nor would call any Israeli ports during the voyage.
If Arab countries' ISP's were to follow the same political philosophy, I
could see them filtering accordingly.
In short, politics.
Is it 'normal'?
Boy, is that a loaded question ;)

So can you give me an example of why and when would an ISP *not* want
its traffic to flow via some other AS(es). Is it a normal policy to
have, and do most of the ISPs have such policies in place?
Thanks,

Hi,
I have a general policy question.
Do the ISPs ever look for some particular AS number in the BGP
AS_PATH and
then decide what action/preference/priority they need to take/give
based on
the AS number(s) present in the BGP AS_PATH_SEQ/SET? For instance,
does it
happen that an ISP receives some BGP paths, but because of some
political,
social, economical, DOS attack, etc. reasons decides that it doesn't
want
to accept this path because some particular AS number is present in
the BGP
UPDATE.
Basically, it doesn't want *its* traffic to flow via that particular AS
number(s).
Or, if there is a mutual disagreement between two ISPs, and one doesn't
want his traffic to traverse the other's AS number.
Does this sort of thing ever happen? Are such restrictive policies
normal
in the ISP/IX scenarios?
Thanks,
Tulip
