- This scenario enables IPComp compression between roadwarrior <b>carol</b> and
- gateway <b>moon</b>. Two IPv6 ICMP requests from <b>carol</b> to <b>alice</b>
- check the established tunnel with compression. The packet sizes are different
- because the kernel does not compress small packets.<br/>
- <b>Note:</b> The kernel applies IPComp after fragmenting the original packet
- according to the MTU. Also, because <b>alice</b> does not know about the IPsec
- tunnel between <b>moon</b> and <b>carol</b> the response to the first ICMP
- request is fragmented in too large fragments and <b>moon</b> sends back ICMPs
- with type 2 to notify <b>alice</b> about this (Path MTU Discovery).
- The second ping is then answered successfully.
