I've just skimmed through RFC 4861 and couldn't see this. I then grepped "disable" (three instances) and I think I found what you mean: Section 6.2.2: "The term "advertising interface" refers to any functioning and enabled interface that has at least one unicast IP address assigned to it and whose corresponding AdvSendAdvertisements flag is TRUE. A router MUST NOT send Router Advertisements out any interface that is not an advertising interface." That leads us to look into "AdvSendAdvertisements" and also wonder whether "at least one unicast IP address assigned" is IPv6 only or includes v4: Section 2.4: "address - an IP-layer identifier for an interface or a set of interfaces. " So that's clear! I started to follow up on AdvSendAdvertisements but it's also a bit random. The standard is a bit wooley. What is the fault you are actually trying to fix?
