COMMENT:
----------------------------------------------------------------------

Hi,

Thanks for this document.

Only one minor comment/question:

(1) p 4, sec 5.1.  The IS-IS IP Algorithm Sub-TLV

   The use of the IP Algorithm Sub-TLV to advertise support for
   algorithms outside the Flex-Algorithm range (128-255) is outside the
   scope of this document.

What does this actually mean if a router receives a SubTlV containing an
algorithm outside the 128-255 range?  Should it ignore, or error? And should
this be specified in this document?  I also note that this is stated here,
under IS-IS, but there is no equivalent text for the OSPF definition, and hence
wanted to ensure that is intentional.

Regards,
Rob
