BGP flooding

So to sum it up you simply can not run into any scaling ceiling with
MP-BGP
architecture.

Flooding nature of BGP requires all the related entities treat
everything, regardless of whether they need it entirely or not.


That is long gone I am afraid ... Hint RFC 4684. Now applicable to more
and more AFI/SAFIs.

Also from day one of L3VPNs, PEs even if receiving all routes were dropping
on inbound (cheap operation) those routes which contained no locally
intersecting RTs.

Thx,
