The in.ripngd daemon implements the Routing Information Protocol next-generation for IPv6 routers (RIPng). RIPng defines the IPv6 equivalent of RIP. When you configure an IPv6 router with the routeadm command and turn on IPv6 routing, the in.ripngd daemon implements RIPng on the router.
The following shows the supported options of RIPng.
n specifies the alternate port number that is used to send or receive RIPnG packets.
Suppresses routing information.
Forces routing information even if the daemon is acting as a router.
Suppresses use of poison reverse.
If in.ripngd does not act as a router, the daemon enters only a default route for each router.
