I can't argue with you there; I'm just thinking of all possible options.

I've already told myself Route Leaking is a no-no, but it's still an 
option - the one that comes after "Option Z".

Of course, vendors will tell you to run pw's to the nearest PE router 
and instantiate a service there, so I'm not turning to them for any 
solution other than hardware. I'll have to twist IP into doing what I 
want :-).

Which is why that 96-port switch from Juniper looks so tasty.

I suppose one could upgrade a 4-port ASR920 to a 12-port, but only if 
there are hardware benefits.

Crap, more (good) vendors need to play in this space.

Loooooove mLDP...

Hehe, woo woo - I'm using that...
