Member Function Documentation

◆ NotifyAddAddress()

void Ipv4ARouting::NotifyAddAddress ( uint32_t  interface,
Ipv4InterfaceAddress  address 
)
inlinevirtual
Parameters
interfacethe index of the interface we are being notified about
addressa new address being added to an interface

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.

Implements ns3::Ipv4RoutingProtocol.

Definition at line 40 of file ipv4-list-routing-test-suite.cc.

◆ NotifyInterfaceDown()

void Ipv4ARouting::NotifyInterfaceDown ( uint32_t  interface)
inlinevirtual
Parameters
interfacethe index of the interface we are being notified about

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

Implements ns3::Ipv4RoutingProtocol.

Definition at line 39 of file ipv4-list-routing-test-suite.cc.

◆ NotifyInterfaceUp()

void Ipv4ARouting::NotifyInterfaceUp ( uint32_t  interface)
inlinevirtual
Parameters
interfacethe index of the interface we are being notified about

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

Implements ns3::Ipv4RoutingProtocol.

Definition at line 38 of file ipv4-list-routing-test-suite.cc.

◆ NotifyRemoveAddress()

void Ipv4ARouting::NotifyRemoveAddress ( uint32_t  interface,
Ipv4InterfaceAddress  address 
)
inlinevirtual
Parameters
interfacethe index of the interface we are being notified about
addressa new address being added to an interface

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.

Implements ns3::Ipv4RoutingProtocol.

Definition at line 41 of file ipv4-list-routing-test-suite.cc.

◆ PrintRoutingTable()

void Ipv4ARouting::PrintRoutingTable ( Ptr< OutputStreamWrapper stream,
Time::Unit  unit 
) const
inlinevirtual

Print the Routing Table entries.

Parameters
streamThe ostream the Routing table is printed to
unitThe time unit to be used in the report

Implements ns3::Ipv4RoutingProtocol.

Definition at line 43 of file ipv4-list-routing-test-suite.cc.

◆ RouteInput()

bool Ipv4ARouting::RouteInput ( Ptr< const Packet p,
const Ipv4Header header,
Ptr< const NetDevice idev,
UnicastForwardCallback  ucb,
MulticastForwardCallback  mcb,
LocalDeliverCallback  lcb,
ErrorCallback  ecb 
)
inlinevirtual

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 Ipv4RoutingProtocol, 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
preceived packet
headerinput parameter used to form a search key for a route
idevPointer to ingress network device
ucbCallback for the case in which the packet is to be forwarded as unicast
mcbCallback for the case in which the packet is to be forwarded as multicast
lcbCallback for the case in which the packet is to be locally delivered
ecbCallback to call if there is an error in forwarding
Returns
true if the Ipv4RoutingProtocol takes responsibility for forwarding or delivering the packet, false otherwise

Implements ns3::Ipv4RoutingProtocol.

Definition at line 35 of file ipv4-list-routing-test-suite.cc.

◆ RouteOutput()

Ptr<Ipv4Route> Ipv4ARouting::RouteOutput ( Ptr< Packet p,
const Ipv4Header header,
Ptr< NetDevice oif,
Socket::SocketErrno sockerr 
)
inlinevirtual

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()

The header input parameter may have an uninitialized value for the source address, but the destination address should always be properly set by the caller.

Parameters
ppacket to be routed. Note that this method may modify the packet. Callers may also pass in a null pointer.
headerinput parameter (used to form key to search for the route)
oifOutput interface Netdevice. May be zero, or may be bound via socket options to a particular output interface.
sockerrOutput parameter; socket errno
Returns
a code that indicates what happened in the lookup

Implements ns3::Ipv4RoutingProtocol.

Definition at line 34 of file ipv4-list-routing-test-suite.cc.

◆ SetIpv4()

void Ipv4ARouting::SetIpv4 ( Ptr< Ipv4 ipv4)
inlinevirtual
Parameters
ipv4the ipv4 object this routing protocol is being associated with

Typically, invoked directly or indirectly from ns3::Ipv4::SetRoutingProtocol

Implements ns3::Ipv4RoutingProtocol.
