Detailed Description

Hold list of Ipv6RoutingProtocol objects.

This class is a specialization of Ipv6RoutingProtocol that allows other instances of Ipv6RoutingProtocol to be inserted in a prioritized list. Routing protocols in the list are consulted one by one, from highest to lowest priority, until a routing protocol is found that will take the packet (this corresponds to a non-zero return value to RouteOutput, or a return value of true to RouteInput). The order by which routing protocols with the same priority value are consulted is undefined.

overridevirtual

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

overridevirtual

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
