Hi All,

It is said that MPLS-VPNs generally consists of a set of sites that 
are interconnected by means of MPLS provider core network and the 
Service providers backbone consists of PE routers and Provider routers.

Now that MPLS forwarding carries packets between PEs routers through the 
service provider backbone , MPLS packet must traverse through the P routers
(if any) in between these PE routers.

My question is how we can be sure that the MPLS-VPN Packet  is really Safe 
when it traverses  through the P routers ? I mean how the corporate information
is still secured when it passes through the P routers ? It is still traversing 
through the Public infrastructure unencrypted .

Any suggestion of yours would be of great help .

Thanks in advance .

Shirish.
