"P" in the above figure refers to a backbone router in the network of a service
provider. P is not directly connected with a CE and is required to have the basic
MPLS capability.
When an ISP wants to utilize the existing IPv4/MPLS network to provide IPv6 traffic
switching capability through MPLS, only the PE routers need to be upgraded.
Therefore, it is undoubtedly a high efficient solution that ISPs use the 6PE
technology as an IPv6 transition mechanism. Furthermore, the operation risk of
the 6PE technology is very low.

IP addresses are configured for interfaces such as VLAN interface, Ethernet
interface, and loopback interface on the device so that they can communicate.
These interfaces serve as the source interface of a tunnel interface to ensure that
the tunnel destination address is reachable.
