Section 4.3 says:

   An MPLS echo request is a UDP packet.  The IP header is set as
   follows: the source IP address is a routable address of the sender;
   the destination IP address is a (randomly chosen) IPv4 address from
   the range 127/8 or IPv6 address from the range
   0:0:0:0:0:FFFF:127/104.

It should say:

   An MPLS echo request is a UDP packet.  The IP header is set as
   follows: the source IP address is a routable address of the sender;
   the destination IP address is a (randomly chosen) IPv4 address from
   the range 127/8 or IPv6 address from the range
   0:0:0:0:0:FFFF:7F00/104.

Notes:

The ":127" is ambiguous (intended to be decimal, but could be hexadecimal).
An alternative fix would be 0:0:0:0:0:FFFF:127.0.0.0/104.
