-- A routing socket message is not generated when an IPv6 address is either inserted or deleted from an interface. The missing routing message problem was discovered by Randall Stewart and Michael Tuxen during SCTP testing. -- Previously when an IPv6 address is configured on an interface, if the prefix length is /128, then a host route is instaleld in the kernel for this address. But this host route is not deleted when that IPv6 address is removed from the interface. -- Routes to the link-local all-nodes multicast address and the interface-local all-nodes multicast address are not removed when the last IPv6 address is removed from an interface.
