void ns3::RipNg::NotifyRemoveAddress	(	uint32_t	interface,
		Ipv6InterfaceAddress	address
	)

virtual

Notify when specified interface add an address.

Protocols are expected to implement this method to be notified whenever a new address is removed from an interface. Typically used to remove the 'network route' of an interface. Can be invoked on an up or down interface.

Parameters

interface	the index of the interface we are being notified about
address	a new address being added to an interface

		MulticastForwardCallback	mcb,

		ErrorCallback	ecb
	)

virtual

Route an input packet (to be forwarded or locally delivered)

This lookup is used in the forwarding process. The packet is handed over to the Ipv6RoutingProtocol, and will get forwarded onward by one of the callbacks. The Linux equivalent is ip_route_input (). There are four valid outcomes, and a matching callbacks to handle each.

Parameters

p	received packet
header	input parameter used to form a search key for a route
idev	Pointer to ingress network device
ucb	Callback for the case in which the packet is to be forwarded as unicast
mcb	Callback for the case in which the packet is to be forwarded as multicast
lcb	Callback for the case in which the packet is to be locally delivered
ecb	Callback to call if there is an error in forwarding

Returns: true if the Ipv6RoutingProtocol takes responsibility for forwarding or delivering the packet, false otherwise

	)

virtual

Query routing cache for an existing route, for an outbound packet.

This lookup is used by transport protocols. It does not cause any packet to be forwarded, and is synchronous. Can be used for multicast or unicast. The Linux equivalent is ip_route_output ()

Parameters

p	packet to be routed. Note that this method may modify the packet. Callers may also pass in a null pointer.
header	input parameter (used to form key to search for the route)
oif	Output interface device. May be zero, or may be bound via socket options to a particular output interface.
sockerr	Output parameter; socket errno
