I have to refer to an appendix to find the full tree diagram. https://tools.ietf.org/html/draft-ietf-rtgwg-yang-vrrp-08#appendix-A, with no forward reference. Why don't you have the full tree in a new section, as you did in https://tools.ietf.org/html/draft-ietf-rtgwg-yang-rip-08#section-3
Thanks for applying the Security Considerations template and noting the sensitive branches.
Please consider updating the example in appendix B to conform to the IAB guidance found at <https://www.iab.org/2016/11/07/iab-statement-on-ipv6/>. This would involve changing the example to use IPv6 instead of IPv4, or adding an IPv6 example in addition to the IPv4 example.
