Detailed Description

Abstract base class for IPv6 routing protocols.

Defines two virtual functions for packet routing and forwarding. The first, RouteOutput (), is used for locally originated packets, and the second, RouteInput (), is used for forwarding and/or delivering received packets. Also defines the signatures of four callbacks used in RouteInput ().

Protocols are expected to implement this method to be notified whenever a new address is added to an interface. Typically used to add a 'network route' on 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

Implemented in ns3::Ipv6BRouting, ns3::Ipv6ARouting, ns3::RipNg, ns3::Ipv6StaticRouting, and ns3::Ipv6ListRouting.

		Ipv6Address	nextHop,
		uint32_t	interface,
		Ipv6Address	prefixToUse = `Ipv6Address::GetZero()`
	)

pure virtual

Notify a new route.

Typically this is used to add another route from IPv6 stack (i.e. ICMPv6 redirect case, ...).

Parameters

dst	destination address
mask	destination mask
nextHop	nextHop for this destination
interface	output interface
prefixToUse	prefix to use as source with this route

Implemented in ns3::Ipv6BRouting, ns3::Ipv6ARouting, ns3::RipNg, ns3::Ipv6StaticRouting, and ns3::Ipv6ListRouting.

		const MulticastForwardCallback &	mcb,
		const LocalDeliverCallback &	lcb,
		const ErrorCallback &	ecb
	)

pure 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

Implemented in ns3::Ipv6BRouting, ns3::Ipv6ARouting, ns3::RipNg, ns3::Ipv6StaticRouting, and ns3::Ipv6ListRouting.

◆ RouteOutput()

virtual Ptr<Ipv6Route> ns3::Ipv6RoutingProtocol::RouteOutput	(	Ptr< Packet >	p,
		const Ipv6Header &	header,
		Ptr< NetDevice >	oif,
		Socket::SocketErrno &	sockerr
	)

pure 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

Returns: a code that indicates what happened in the lookup

Implemented in ns3::Ipv6BRouting, ns3::Ipv6ARouting, ns3::RipNg, ns3::Ipv6StaticRouting, and ns3::Ipv6ListRouting.

◆ SetIpv6()

virtual void ns3::Ipv6RoutingProtocol::SetIpv6 ( Ptr< Ipv6 > ipv6 )

pure virtual

Typically, invoked directly or indirectly from ns3::Ipv6::SetRoutingProtocol.

Parameters

ipv6	the ipv6 object this routing protocol is being associated with
