We're testing half of the internet instead<br>of our GGSN. Let's use the IPv6 address of the docker container<br>running the test sute, which is guaranteed to always exist. We have<br>no problems with routing, as the ICMPv6 is hand-crafted and encapsulated<br>into GTP before it's sent to the kernel IP stack - so basically on the<br>transmit side, the kernel doesn't know anything about the destination<br>address of the encapsulated IPv6 packet.<br><br>Change-Id: I1377ffa2cc6980168297d5ff5c81fa5dad94d7a9<br>---<br>M ttcn3-ggsn-test/GGSN_Tests.cfg<br>M ttcn3-ggsn-test/osmo-ggsn.cfg<br>2 files changed, 3 insertions(+), 2 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.osmocom.org:29418/docker-playground refs/changes/72/19672/1</pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;"><span>diff --git a/ttcn3-ggsn-test/GGSN_Tests.cfg b/ttcn3-ggsn-test/GGSN_Tests.cfg</span><br><span>index 064bf37..36603c8 100644</span><br><span>--- a/ttcn3-ggsn-test/GGSN_Tests.cfg</span><br><span>+++ b/ttcn3-ggsn-test/GGSN_Tests.cfg</span><br><span>@@ -17,6 +17,7 @@</span><br><span> GGSN_Tests.m_ggsn_ip_gtpu := "172.18.3.201"</span><br><span> # GGSN announced DNS address</span><br><span> GGSN_Tests.m_ggsn_ip4_dns1 := "172.18.3.201"</span><br><span style="color: hsl(120, 100%, 40%);">+GGSN_Tests.m_ggsn_ip6_dns1 := "fd02:db8:3::201"</span><br><span> </span><br><span> [EXECUTE]</span><br><span> GGSN_Tests.control</span><br><span>diff --git a/ttcn3-ggsn-test/osmo-ggsn.cfg b/ttcn3-ggsn-test/osmo-ggsn.cfg</span><br><span>index 7dff25f..972ee93 100644</span><br><span>--- a/ttcn3-ggsn-test/osmo-ggsn.cfg</span><br><span>+++ b/ttcn3-ggsn-test/osmo-ggsn.cfg</span><br><span>@@ -58,7 +58,7 @@</span><br><span> tun-device tun6</span><br><span> type-support v6</span><br><span> ipv6 prefix dynamic 2001:780:44:2000:0:0:0:0/56</span><br><span style="color: hsl(0, 100%, 40%);">- ipv6 dns 0 2001:4860:4860::8888</span><br><span style="color: hsl(120, 100%, 40%);">+ ipv6 dns 0 fd02:db8:3::201</span><br><span> ipv6 dns 1 2001:4860:4860::8844</span><br><span> ipv6 ifconfig 2001:780:44:2000:0:0:0:0/56</span><br><span> no shutdown</span><br><span>@@ -71,7 +71,7 @@</span><br><span> ip dns 1 8.8.8.8</span><br><span> ip ifconfig 176.16.46.0/24</span><br><span> ipv6 prefix dynamic 2001:780:44:2100:0:0:0:0/56</span><br><span style="color: hsl(0, 100%, 40%);">- ipv6 dns 0 2001:4860:4860::8888</span><br><span style="color: hsl(120, 100%, 40%);">+ ipv6 dns 0 fd02:db8:3::201</span><br><span> ipv6 dns 1 2001:4860:4860::8844</span><br><span> ipv6 ifconfig 2001:780:44:2100:0:0:0:0/56</span><br><span> no shutdown</span><br><span></span><br></pre><p>To view, visit <a href="https://gerrit.osmocom.org/c/docker-playground/+/19672">change 19672</a>.
