[c-nsp] data center/mpls/vpls

[Gabor Szabo (gabszabo)]

Hi Aaron,

Have you checked the ASR9K nV Satellite feature with 9000v which can be placed physically as TOR device but works as a remote linecard for the ASR9K? You can have every service on satellite ports what you have on local interface of the ASR9K...

It is generally not recommended / preferred architecture for hosting / complex DC (where the Nexus family is our strong preference) but can fit for collocation type of services...

Regards,
Gabor
