Hi Bill, Further to:
http://www.irtf.org/pipermail/rrg/2008-October/000079.html http://www.irtf.org/pipermail/rrg/2008-October/000080.html as with APT (and I think LISP, Six/One Router and your own TRRP proposal), Ivip doesn't replace BGP in a global sense. If every user network which was not on PA space from their ISP adopted Ivip SPI (Scalable PI) space by renting it from some MAB (Mapped Addres Block) company, then ISP networks would still all be using BGP. If an end-user network currently has conventional BGP-managed PI space, and relinquishes this so they can use rented SPI space within a MAB of some MAB company, then as far as this end-user network, Ivip is "replacing BGP", because the network never needs to use BGP after this. If an end-user network with conventional BGP-managed PI space converts their prefix (or prefixes) into a MAB (or MABs) then they are still using BGP, since each MAB is a single advertised prefix in BGP. However, they can split the MAB into as many micronets as they like, which gives a great routing scaling advantage compared to them splitting their prefix into multiple separately advertised prefixes. - Robin _______________________________________________ rrg mailing list [email protected] https://www.irtf.org/mailman/listinfo/rrg
