Hi,
I thought that these AS is for "the company" (which is originally defined
by my previous e-mail), right? Then, sorry but I wonder if "a site" and
"Autonomous System" is not same.

><NLA1-1>-----<NLA2-1>
Both NLA1-1 and NLA2-1 is allocated to "the company". and I belive
that NLA1-1 and NLA2-1 are different sites. i.e. "the company" has
two sites.
And I select definition of the term AS from rfc 1771;
> The use of the term Autonomous System
> here stresses the fact that, even when multiple IGPs and metrics are

I thought that "the company" operate this two NLA network with same routing
plan, we can consider that a set of NLA1-1 and NLA2-1 is same AS, but
the line between TLA1 and NLA1-1 will not present any reachability to anyone
in IPv6 Grobal Network, so I also belive this set (of NLA1-1 and NLA2-1) is not
one AS.
Greg idea that this set has two AS is right in some part. But if
NLA1-1(=site=AS) and NLA2-1(=site=AS) was operated with same IGP,
Are these two AS is different AS ??
I belive a site is a site. That is not more or less.
The concept of AS or NLA holder has no relationship with concept of site,
What do you think about it ?
