That is what I thought but I get confused since whenever I look at DVIPA discussions like this
https://www.ibm.com/docs/en/zos-basic-skills?topic=addressing-unique-application-instance-dvipa it always shows a CF. But in this preso from IBM at Share https://share.confex.com/share/125/webprogram/Handout/Session17284/Sysplex%20and%20Network%20Technologies%20and%20Considerations%20%28Summer%202015%29.pdf there is no mention of a CF anywhere in the deck. Looks like it just uses XCF to communicate the status of the DVIPA stack between the TCP/IP stacks on each LPAR as you say.
