RE: Ethernet over MPLS

Guys,

       If we look at the blue print it is mentioned about L2tpv3, Layer 2 VPNS
and other stuff. I believe the AToM, xconnects and the Interworking will be
convered according to the Lab blue print. I'll recomend reading MPLS in Cisco
IOS book, as the topics covered in this book are very close to the Lab exam
Blue print for SP.

Thanks,

Ahmad Bilal
