Re: a different proposal for ipv6 in bgp

[Tony Li <[e-mail]>]

   I can't say for all, but for some ISPs the size of BGP policy database
   way exceeds the size of all other bgp data structures including RIB and
   hence is a real issue. 

That's a very interesting claim and I'd like to understand it in more
detail.  Could you precisely define what the "policy database" is?  Are we
just talking about the administrative filters?  Or are we talking about
database of paths?  If the latter, are AS path strings separated from the
RIB?

In one particular implementation that I'm familiar with, the dominant
memory consumer is the RIB, and that's by several orders of magnitude.  In
that implementation, the AS path strings are separated from storage in the
RIB.
