Just wondering from those in the know, whether it's best practice to implement public or private IP's for the PE-to-CE link. What's everyone using and why? For our MPLS network, I've been asked by my Manager to use private IP's for the PE-CE link in order to give the customer the appearance that they are on a secure PRIVATE network due to private IP's being used. Although I tend to be more fond of using public IP's because it's a unique address space so you don't have to worry about overlapping IP addresses on the customer's end and secondly there's no configuration from the Service Provider's end should you need to remove the connection from the VRF to conduct further testing from the Internet becuse the connection is already using public IP's (eg: for cases where the customer is complaining of slow speeds, packet loss, drop outs, etc and you want to test the individual connection and bypass their VPN). Thanks. Andy
