Re: Ethernet over MPLS

Hi,

Sorry but I don't have that book and was wondering about the QinQ method.

Is the "xconnect {destination vc-id encapuluation mpls} " replacing
the "mpls l2transport route" or vice-versa? Which should we be
concerned with for the hardware/IOS on the SP exam?

Thanks
Rich
