I have reviewed this document as part of the security directorate's ongoing
effort to review all IETF documents being processed by the IESG.  These
comments were written primarily for the benefit of the security area directors.
Document editors and WG chairs should treat these comments just like any other
last call comments.

The document is short and well-written. The security considerations section is
also short and redirect readers to referenced documents: [I-D.ietf-rtgwg-vrrp-rfc5798bis],
[RFC5880], [RFC5881], and [RFC8562]. I agree that this is an appropriate list
of documents to consult when reviewing security of the overall system.
