Re: IPv8 / BGP8 / CF

Saron

That's a great question

They'll stay on ipv4 with a firewall or gateway that has xlate8 on it. It
sees www.myipv8.com

card 10.10.50.10
zs inside add 10.10.50.253
Zs outside 2203.12.34.50.2 /30
12345.12.34.56.78 as www.myipv8.com

1. Ipv4 queries zs addrbyname
2. Dbs returns a8 12345.12.34.56.78
3.  Xlate8 knows it came from an ipv4 client
4. Xlate pushes the rule into mftables

ipv4 to ipv8

src ---------- dst  xlate  ---src - dest

10.10.50.10  -- 10.10.50.254 xlate
     2203.12.34.50.2 -- 12345.12.34.56.78

No encapsulation needed.

If it crosses a boundary that exits ipv4 then that ipv8 router does an
8over4 and forwards it.

Ipv8 is ipv4 v2

You never have to upgrade an IPv4 client to operate in an IPv8 environment

Ipv8 is ipv4 v2.
