Dear all,
Can someone point me to where are held the IANA allocation for the
values in the 'protocol' field of the Label Stack Sub-TLV of the
Downstream Detailed Mapping TLV?

There is draft-ietf-mpls-spring-lsp-ping-01 which is adding IS-IS and
OSPF as new values into this field but I fail to find where these are
maintained.

<tp>

My reading would be that there is no such registry.  The new sub-TLV
appear at
http://www.iana.org/assignments/mpls-lsp-ping-parameters/mpls-lsp-ping-p
arameters.xml#sub-tlv-1-16-21
where for e.g. 34 the reference is to the I-D that you cite, with no
more details.

Not all names and numbers appear in an IANA registry; setting up and
maintaining a registry takes work and sometimes it is not worth it.  If
the only use is local to the one field and only in the one RFC, then it
may not be worth it.

Tom Petch

Regards,
Mustapha.
