Hi all,
IMHO and FWIW this Erratum is obviously valid.
However, I am not sure it is really a Technical one and not just an Editorial  (report of a typo).

AFAIK  recursive opaque FEC in mLDP is used for setup of non-segmented inter-domain/inter-AS P2MP LSPs for intra-AS mVPN I-PMSI routes for years.

My 2c.

Subject: [EXTERNAL] [mpls] [Technical Errata Reported] RFC6512 (6754)

The following errata report has been submitted for RFC6512,
"Using Multipoint LDP When the Backbone Has No Route to the Root".

--------------------------------------
You may review the report below and at:
https://clicktime.symantec.com/36qYGHSu9z4s4gec2QGgaMp6H4?u=https%3A%2F%2Fwww.rfc-editor.org%2Ferrata%2Feid6754

--------------------------------------
Type: Technical
Reported by: Bert Van Ael <bert.van.ael@nomios.be>

Section: 3.2.1

Original Text
-------------
PE1 also has this Inter-AS I-PMSI A-D route.

Corrected Text
--------------
PE1 also has this Intra-AS I-PMSI A-D route.

Notes
-----
"PE1 also has this route" refers to "Although ASBR1 does not have a route to PE2, it does have a BGP Intra-AS Inclusive PMSI (I-PMSI) auto-discovery (A-D) route". Intra-AS mechanisms are used for auto-discovery/binding for Non-Segmented Inter-AS Tunnels.
