Hi Robin,

That's not really true of TRRP. TRRP doesn't replace BGP, it
supplements BGP. At the end of the day, the individual network
operators decide which prefixes are allowed into whatever remains of
their respective BGP tables and which must use map-encap to transit
their network. Addresses remaining in BGP are usable for all purposes
they're now used for, plus providing TRRP exits and map servers.
Although I didn't describe it this way, the practical result should be
a balance affected as much by who is willing to pay to be in the BGP
table as much as it is by the overall table size.

In other words, the deployment of TRRP should, in theory, bring about
a natural, economically-driven balance between BGP-based large sites,
TRRP-based sites of various sizes and provider-aggregated sites of
various sizes.

Regards,
Bill Herrin
