[c-nsp] Layer 2 local switching for QinQ circuits

[David Freedman]

Bridging was also suggested, but I dont think this would be suitable
since we are talking about a couple of 100 Megs of traffic with lots of 
multicast :)

Does anybody know what kind of performance gain provided by using l2 
local switching over bridging?

I can't find much documentation on this, I'm assuming that because
l2 local switching was developed with CEF in mind it should have bad 
things about it, but I could be wrong...

Dave.
