Section 4.1.1.1.1. and 4.2.1. says:

Original Text
-------------
4.1.1.1.1.) "When an SR P2MP P-tunnel is not shared across MVPNs, i.e., there 
is one-to-one association between an EVI and an SR P2MP P-tunnel, the MPLS 
Label field is set to zero as per [RFC6514]. In this case, the SR-MPLS Tree-SID 
of the PTI of the SR P2MP Policy advertised in the P-tunnel is sufficient to 
identify the MVPN instance for delivering the payload."

4.2.1.) "PE1 will encapsulate the MVPN payload into the MPLS label stack <L1, 
L2, L3, L10> with L10 as the BoS label."

Corrected Text
--------------

field is set to zero as per [RFC6514]. In this case, the SR-MPLS Tree-SID of 
the PTI of the SR P2MP Policy advertised in the P-tunnel is sufficient to

L2, L3, L10> with L10 as the BoS label."

Notes
-----
Claim from Submitter:
==============
In section 4.1.1.1.1, two occurrences of "MVPN" appear to be copied from 
Section 3.2.1.1.
In section 4.2.1, "MVPN payload" should be "EVPN payload" (copied from 3.3.1).

AD Review Notes:
============
* In Section 4.1.1.1.1, the two uses of “MVPN” are inconsistent with the EVPN 
context and with the remainder of the section, which describes sharing the 
P-tunnel across EVIs and using the label to identify the corresponding EVI.
* Similarly, Section 4.2.1 describes EVPN ingress replication, including an 
IMET A-D route and an EVPN BUM label. The payload is therefore an EVPN payload, 
not an MVPN payload.
* The proposed corrections accurately resolve these copy-and-paste errors and 
do not change the specified protocol behavior.
