Constructor Detail

IcmpHandler

public IcmpHandler(SegmentRoutingManager srManager)

Creates an IcmpHandler object.

Parameters:

srManager - SegmentRoutingManager object

Method Detail

processIcmp

public void processIcmp(org.onlab.packet.Ethernet eth,
                        org.onosproject.net.ConnectPoint inPort)

Process incoming ICMP packet. If it is an ICMP request to router, then sends an ICMP response. Otherwise ignore the packet.

Parameters:

eth - inbound ICMP packet

inPort - the input port

processIcmpv6

public void processIcmpv6(org.onlab.packet.Ethernet eth,
                          org.onosproject.net.ConnectPoint inPort)

Process incoming ICMPv6 packet. If it is an ICMPv6 request to router, then sends an ICMPv6 response. Otherwise ignore the packet.

Parameters:

eth - the incoming ICMPv6 packet

inPort - the input port

processPacketIn

public void processPacketIn(org.onosproject.net.neighbour.NeighbourMessageContext pkt,
                            org.onosproject.net.host.HostService hostService)

Process incoming NDP packet. If it is an NDP request for the router or for the gateway, then sends a NDP reply. If it is an NDP request to unknown host flood in the subnet. If it is an NDP packet to known host forward the packet to the host. FIXME If the NDP packets use link local addresses we fail.

Parameters:

pkt - inbound packet

hostService - the host service

sendNdpRequest

public void sendNdpRequest(org.onosproject.net.DeviceId deviceId,
                           org.onlab.packet.IpAddress targetAddress,
                           org.onosproject.net.ConnectPoint inPort)

Sends a NDP request for the target IP address to all ports except in-port.

Parameters:

deviceId - Switch device ID

targetAddress - target IP address for ARP

inPort - in-port
