[c-nsp] Core to access links. Use single etherchannel?

[Holemans Wim]

But the 'path cost' changes (becomes higher if a member of the channel
goes down)  which can cause a recalculation of the STP for links further
down the path...

No, an Etherchannel is a single link as far as STP is concerned, and
members coming or going will happen 'below' the STP level.
