Hi,
We are planning to establish an new office which will have three building and more than 8000 ports.
L2 topology will look like below, with VSS implemented at Data center and building core level. (on cisco 6509)
Now challenge is to implement path isolation techniques for different VLANs at each block accessing respective services at Data center.
planning to do the same with MPLS VPN, however not able to get configuration examples, best practices and concerns if any.
Though CISCO forum is the best place to seek help from.

Regards,
MSG
