Description

From build 667 onwards, TC_pdp6_act_deact_gtpu_access is failing both in 'latest' and in 'master': https://jenkins.osmocom.org/jenkins/view/TTCN3/job/ttcn3-ggsn-test-latest/test_results_analyzer/

We merged https://gerrit.osmocom.org/c/docker-playground/+/19572 the night before. But all that does is enalbe IPv6 on the docker network between containers. Needs investigation.

  • Status changed from New to In Progress

comparing the two pcap files of old (passing) and new (failing) tests, it can be seen that in the old (passing) pcap, we have "ICMPv6 destination unreachable" for each ICMPv6 echo request that is sent.

In the new (failing) case, no such messages are received (presumably as we now have a default route that routes the packets somewhere?).

Indeed, we are sending an ICMP echo req, and expect to either receive a response, or an ICMPv6 error. But now with the default route in place, we get neither:
