rRK is equivalent to rDSRK, See section 2:
The re-authentication Domain-Specific Root Key (rDSRK) is a
re-authentication Root Key (rRK) [RFC6696] derived from the Domain-
Specific Root Key (DSRK) instead of the EMSK.

RFC6942 support transportation of rDSRK. When ER server change, new rDSRK needs to be generated and transported to the new ER server.
The peer in RFC6696 is referred to ER client not Diameter Peer.

Hi folks

I was reading 6696 and 6924 (it's been awhile)  and I need clarification:

1) It appears that 6924 does not support transportation of DSRK key. 
Only rRK and rMSK.  Is that correct?

2) According to RFC 6696 - section 4.2:

RFC 6696: Section 4.2:

     o  The rRK MUST remain on the peer and the server that derived it and MUST NOT be transported to any other entity.

So why is 6942 transporting the rRK around?
