with the advent of vlan tags, the whole idea of CSMA for IXP
networks is passe.
just put each pair of peers into their own private tagged vlan and
let one of
them allocate a V4 /30 and a V6 /64 for it. as a bonus, this
prevents third
party BGP (which nobody really liked which sometimes got turned on
by mistake)
and prevents transit dumping and/or "pointing default at" someone.
the IXP no
longer needs any address space, they're just a VPN provider.
shared-switch
connections are just virtual crossconnects.
Large IXP have >300 customers. You would need up to 45k vlan tags,
wouldn't you?
QinQ could solve this
not really
painfully, with multiple circuits into the IX :) I'm not advocating
Paul's suggestion at all here
