Mark,

Nope .. it is the other way around.

It is all easy if you look from your network centric view.

But if I am connected to 10 ISPs in each POP I have to build 10 different egress policies, each embedding custom policy, teach NOC to understand it etc...

I think if there is a defined way to express prepend N times to my ISP peers across all uplinks or lower local pref in my ISP network in a same way to group of ISPs I see the value.

Best Regards,
R.

Exactly Mike!

The Idea would be to define some base levels, to make the creations of route-filtering simpler to everyone in the world.
And what comes beyond that, is in charge of each autonomous system.

It would make the scripting and templates easier and would avoid fat-fingers.

Are we saying that what individual operators design for their own networks is "complicated", and that coalescing around a single "de facto" standard would simplify that?
