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

Section: 3

Original Text
-------------


Corrected Text
--------------
(At the end of the section)

In case of OSPF while router advertises maximum cost, virtual link(s)
that cross link under question, could be broken. This is because
virtual link, which underlying path has cost greater than 0xFFFF,
considered as inoperational. As a result, virtually connected area(s)
could be isolated from backbone.

Notes
-----
In case there are two or more links on path taken by virtual link, and one of them has max link cost, path metric will exceed value 0xffff. As a result virtual link will become inoperational.

Instructions:

rejected. When a decision is reached, the verifying party (IESG)
