      net.clackrouter.component.simplerouter.ICMPDemux

All Implemented Interfaces:

Alarm

public class ICMPDemux
extends ClackComponent

Demultiplexes a subset of ICMP types to different output ports.

Currently demultiplexed are the following types: Echo Request, Destination Unreachable, Echo Reply, and TTL-Exceeded. An additional output takes all other ICMP types.
