Subject: RE: FW: 3gpp scenario 2

[BGP] could theoretically be used, but its main area of applicability is
to enable automatic tunneling over IPv4-enabled core using IPv4/6 edge
routers (the typical case being an ISP's MPLS core network).  If this was
applied to the general Internet, it would basically mean that
participating islands would have to be have BGP sessions between them
using some tunneling techinique like 6to4, IPv4 eBGP multihop, etc.

So it seems to me neither of these is applicable in the context 2).

---

<<iLS>> [BGP] defines 2 different deployment options: the first one assumes MP-BGP implementation over IPv4 (identification of MP-BGP edge routers by their IPv4 addresses, using trivial 6in4 tunneling), while the second one assumes MP-BGP implementation over IPv6, thus needing to rely on some existing tunneling technique (as you mentioned before). Why can't we just consider the first approach, avoiding the need for any additional tunneling mechanisms?

Br,
