Check RFC1771 (BGP) and/or the ~= "OSPF to BGP Interaction" RFC (I don't know
the number).
I remember something about setting the tag to the neighbor AS#. I think newer
Cisco IOS does this by default.
The intent was if you redistribute BGP into the IGP and then back into BGP on
the other side of your AS then BGP path info could be maintained. I think in
practice this proved to be impractical. The problem is that the tag field is
not big enough to hold the entire AS path - so BGP AS path loops can not be
totally eleminated with this method.
