[c-nsp] CRS-3: FC140/S, FP140 & 14X10GBE (Emanuel Popa)

[Андрей Нуштаев]

Hi, Emanuel.

Hope that information will be still usefull for you.

a. FP140/MSC40 works well together.
b. Unfortunately, I didn't use 3rd party XFP.
c. No problem with IOS-XR 4.0.1-px on P router (ISIS/LDP) and AS border
router (BGP IPv4/IPv6).
d. No support of L3/L2 VPN forwarding when you have FP140 card in the
current version (4.0.1), no QoS support per subinterface for FP140
(including classification/remarking).

Andrey
