Member Function Documentation

◆ AddBridgePort()

void ns3::BridgeNetDevice::AddBridgePort ( Ptr< NetDevice > bridgePort )

Add a 'port' to a bridge device.

Parameters

bridgePort the NetDevice to add

This method adds a new bridge port to a BridgeNetDevice, so that the new bridge port NetDevice becomes part of the bridge and L2 frames start being forwarded to/from this NetDevice.

Attention: The netdevice that is being added as bridge port must not have an IP address. In order to add IP connectivity to a bridging node you must enable IP on the BridgeNetDevice itself, never on its port netdevices.

Here is the call graph for this function:

◆ AddLinkChangeCallback()

void ns3::BridgeNetDevice::AddLinkChangeCallback ( Callback< void > callback )

overridevirtual

Parameters

callback the callback to invoke

Add a callback invoked whenever the link status changes to UP. This callback is typically used by the IP/ARP layer to flush the ARP cache and by IPv6 stack to flush NDISC cache whenever the link goes up.

Implements ns3::NetDevice.

Definition at line 332 of file bridge-net-device.cc.

◆ DoDispose()

void ns3::BridgeNetDevice::DoDispose ( )

overrideprotectedvirtual

Destructor implementation.

This method is called by Dispose() or by the Object's destructor, whichever comes first.

Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.

It is safe to call GetObject() from within this method.

Reimplemented from ns3::Object.

Here is the caller graph for this function:

◆ GetMulticast() [1/2]

Address ns3::BridgeNetDevice::GetMulticast ( Ipv4Address multicastGroup ) const

overridevirtual

Make and return a MAC multicast address using the provided multicast group.

RFC 1112 says that an Ipv4 host group address is mapped to an Ethernet multicast address by placing the low-order 23-bits of the IP address into the low-order 23 bits of the Ethernet multicast address 01-00-5E-00-00-00 (hex). Similar RFCs exist for Ipv6 and Eui64 mappings. This method performs the multicast address creation function appropriate to the underlying MAC address of the device. This MAC address is encapsulated in an abstract Address to avoid dependencies on the exact MAC address format.

In the case of net devices that do not support multicast, clients are expected to test NetDevice::IsMulticast and avoid attempting to map multicast packets. Subclasses of NetDevice that do support multicasting are expected to override this method and provide an implementation appropriate to the particular device.

Parameters

multicastGroup The IP address for the multicast group destination of the packet.

Returns: The MAC multicast Address used to send packets to the provided multicast group.

Warning: Calling this method is invalid if IsMulticast returns not true.
