Ensure ndpd-host is not in use
MediaNivel 1Automatizadaaix
Descripción
This entry starts ndpd-host on system startup. This is the Neighbor Discovery Protocol (NDP) daemon. The ndpd-host command handles the default route, which includes the default router, the default interface, and the default interface address. However, the ndpd-host command does not overwrite the static default routes that are set on the host. Audit: the ndpd-host start line in /etc/rc.tcpip must be commented out and the ndpd-host subsystem must not be active.
