Hi Ridolfi,
 
Yes, it is possible that the traffics are only between A-B and A-C. But, if B and C have the same IP space, when a terminal in A want to send a packet to 10.0.0.2, how can it tells it's the 10.0.0.2 in B or 10.0.0.2 in C? It has no idea of VPN.

Hi Sylvia,

for extranet service we have 3 VPNs; VPN A is the central office,  B and C are 2 branch , and 2 VPNs  whit same IP space; it's possible only the traffic A-B, and A-C; In the VRFof VPN A  is not possible to have   the same network for VPNs B and C.

The idea is to use NAT in B or C and to advertise the NAT Pool from B or C to A.

Hi,
 
Sorry, what do you mean by "natting IP between 2 VPN"?
 
The private IP addresses are seen only inside VPNs. One VPN has no any idea about the IP address in the other VPN.
For the PE router, it only knows VPN-IPV4 address family.

Hi all,

Is it possible to use NAT feature for natting IP between 2 VPN ?

Any idea about the restriction on cisco site:"Inside VPN to VPN with NAT is not supported" ?
