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 ().

Doxygen introspection did not find any typical Config paths.
No Attributes are defined for this type.
No TraceSources are defined for this type.

TypeId ns3::Ipv6RoutingProtocol::GetTypeId ( void )

static

Reimplemented from ns3::Object.

Reimplemented in ns3::Ipv6StaticRouting, and ns3::Ipv6ListRouting.

Here is the call graph for this function:

virtual void ns3::Ipv6RoutingProtocol::NotifyAddAddress	(	uint32_t	interface,
		Ipv6InterfaceAddress	address
	)

pure virtual

Notify when specified interface add an address.

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::Ipv6StaticRouting, ns3::Ipv6ListRouting, Ipv6BRouting, and Ipv6ARouting.

Referenced by ns3::Ipv6L3Protocol::AddAddress().

Here is the caller graph for this function:

virtual void ns3::Ipv6RoutingProtocol::NotifyAddRoute	(	Ipv6Address	dst,
		Ipv6Prefix	mask,
		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::Ipv6StaticRouting, ns3::Ipv6ListRouting, Ipv6BRouting, and Ipv6ARouting.

Here is the caller graph for this function:

virtual void ns3::Ipv6RoutingProtocol::NotifyInterfaceDown ( uint32_t interface )

pure virtual

Notify when specified interface goes DOWN.

Protocols are expected to implement this method to be notified of the state change of an interface in a node.

Parameters

interface the index of the interface we are being notified about

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

Here is the caller graph for this function:

virtual void ns3::Ipv6RoutingProtocol::NotifyInterfaceUp ( uint32_t interface )

pure virtual

Notify when specified interface goes UP.

Protocols are expected to implement this method to be notified of the state change of an interface in a node.

Parameters

interface the index of the interface we are being notified about

Here is the caller graph for this function:

virtual void ns3::Ipv6RoutingProtocol::NotifyRemoveAddress	(	uint32_t	interface,
		Ipv6InterfaceAddress	address
	)

pure 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

		Ptr< const NetDevice >	idev,
		UnicastForwardCallback	ucb,
		MulticastForwardCallback	mcb,
		LocalDeliverCallback	lcb,
		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::Ipv6StaticRouting, ns3::Ipv6ListRouting, Ipv6BRouting, and Ipv6ARouting.

Referenced by ns3::Ipv6L3Protocol::Receive().

Here is the caller graph for this function:

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
