--------------------------------------
Type: Technical
Reported by: Alexander Okonnikov <alexander.okonnikov@gmail.com>

Section: 3

Original Text
-------------
   The label(s) specified for a particular route (and associated with
   its address prefix) must be assigned by the LSR which is identified
   by the value of the Next Hop attribute of the route.

   When a BGP speaker redistributes a route, the label(s) assigned to
   that route must not be changed (except by omission), unless the
   speaker changes the value of the Next Hop attribute of the route.

Corrected Text
--------------
   The label(s) specified for a particular route (and associated with
   its address prefix) must be assigned by the LSR which is identified
   by the value of the Network Address of Next Hop field of
   MP_REACH_NLRI attribute of the route.

   When a BGP speaker redistributes a route, the label(s) assigned to
   that route must not be changed (except by omission), unless the
   speaker changes the value of the Network Address of Next Hop field of
   MP_REACH_NLRI attribute of the route.

Notes
-----
Next Hop address for labeled routes is conveyed within MP_REACH_NLRI attribute.
