( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/27092 ) Change subject: ggsn: Expect no linklocal-addr forwarding when testing open5gs ...................................................................... ggsn: Expect no linklocal-addr forwarding when testing open5gs It's not really clear whether GTP should really be forwarding packets with link-local address outside the tunnel. In theory the link-local address should be used to communicate with the GGSN in order to get the global link address, that's it. Running against open5gs it can be observed that they are not forwarded, while osmo-ggsn forwards them correctly. Since it seems more like an implementation dependent detail, let's accept any and adapt expectancies depending on what are we testing, this way it ends up documented the current situation in case it ever changes in the future.
