Hi all,
I don't know if the following question has already been discussed, but I
haven't found information on the net.
Consider the following topology:
Server ---- AFTR ---- Router ---- B4 ---- host
The host communicate with the server and the server reply to the host.
There is a DS-Lite tunnel between the "B4" element and the "AFTR" element.
Consider a link failure between the "Router" and the "B4".
When a packet comes from the server in direction of the host, the
"router" generates an ICMPv6 destination unreachable message in
direction of the "AFTR" element.
My question is: What is required from the AFTR element in this situation ?
- Does the "AFTR" needs to drop the packet ?
- Does the "AFTR" needs to convert the ICMPv6 in an ICMPv4 ?
- something else ?
The great advantage of DS-Lite is that it doesn't have to convert packet
from one protocol to another. Converting an ICMPv6 in an ICMPv4
considerably complicate the "AFTR" element.
Thank you
