Re: IPv8 / BGP8 / CF

Shrihari,

The point I'm trying to work thru right now is the fib has a field to mark
forwarding for v4vpn type ii and if for the asn i make a vrf = asn and an
rd of asn:65535 i might be able to avoid tunneling and use the silicon
while in transition.

Ipv8 is not a 64 bit address its an 32bit asn postal code.

And a 32 ipv4 address.
