Hi,
The VPNs in MPLS are catogrized into two Types:
1- Peer to peer VPN.
2- Overlay VPN.
Now, The Categories of a VPN could be , 1- full mesh . 2- Partial mesh . 3- Centeral services.
With regard to your OSPF redistribution question, could you elaborate more on the exact problem you are facing? where exactly you are applying the redistrbution of OSPF here?
Regards,
Mohamed
