Also keep in mind;

single-homed networks never need full-table..

multi-homed networks could also do default routing just packet-mark incoming interface and then route packets out via same interface..

I do not see gain in running BGP full-table, _*excluding*_ networks using Intelligent routing optimizers that run jitter and ping tests..

but these are just my ideas.., i respect all ideas.. we are here to discuss..

There are people running full-table of v4 and v6 _*just for fun*_... I guess it makes them happy when they look thousands of routes available on single interface!

I am pretty sure Tier-1 and Tier-2 networks have enough money for upgrades. But i may be wrong. What do you think?

Thanks and regards

how would you route 800 Gigabit-ethernet that will soon be released as IEEE standart?

we were paying 1 usd per megabit several years ago. now it is as low as 4 usd cent.

As i said before, the future is coming just now. There must be ways to increase CPU caches and memories of routers.

It is also about wholesale. When you buy cheaper routers, powerful routers stay expensive.

But when everybody upgrades, memory and processor unit prices decrease.. Vendors gain from demand.

Others use an expensive kind of memory
called a TCAM that's very fast but both expensive and power hungry, so
generally not sized for huge numbers of tiny routes.
