If it does, that's bad... You should never see IPv4 mapped addresses
on the wire.
They should only be an internal representation of an IPv4 packet
within the host.

Hi,
Per my understanding, it is not required to have ipv6 address in
loopback intf on all P routers inorder to have 6PE work. If I remember
it correctly, P router will use ::FFFF::<ipv4-addr> while originating
ICMPv6 error message.

I was just wondering , while I'm planning my network to support
6PE/6VPE why should i assign an IPv6 for Loopbacks?
Maybe it's needed for Point-Point links or external interfaces
between
my peers, but anyone here know why i should assign IPv6 for all my
Routers inside my ISP if we will run PE/6VPE not dual stack.
Otherwise the intermediate P devices do not have an address to
source
ICMPv6 "hop count exceeded" error replies => traceroute doesn't work
properly.
Best regards,
