[f-nsp] QinQ on FLS

[Alain Hebert]

     Well,

     As a Metro provider, trying to find devices to offer 802.1ad at the 
customer (CE's) is a pricey proposition...
     ( Our pipes can pass thru anything from dark fiber to cup&string 
links )

     The way the vendor are separating the 802.1ad, 802.1ah and MPLS 
features from the 802.1Q is getting annoying.

     Beside MPLS, the other are quite static in term of setup and from 
my experience with FPGA, this shouldn't be a stopping block.

     Right now the cheapest device for a CE is a Cisco ME3400EG ( 4 x 
1Gbps ) at ~$4k each :( while 28 ports 10Gb switches only cost ~$7k.

     PS: As for MPLS, the ~$10k tax most Vendor ask to have it in Core 
devices is sickening...
