I want to thank everyone who responded to my request. The responses
were/are overwhelming.

I've found some essential design flaws in my network when dealing with
BGP routing that is carried over proto41 tunnels.

These flaws are most likely prevented within the normal
vXiBGP-vXIGP-vXiBGP scope, but if anyone is interested in discussing it
further, I'll gladly do so, and document my findings.

Perhaps my small ISP test platform using tunnels isn't a great example,
but I've found that balance is certainly important, and overlooking
simple things is quite easy to do.

On another topic regarding v6 that will eventually have to be discussed,
who is filtering at what prefixlen? I'm doing /48.

I'm deathly afraid of someone breaking up a bunch of /32s into /48s (or
/64s if you don't filter) and overwhelming our routers. Is there a BCP
list to follow regarding prefix filtering?

Steve
