Pau Espin Pedrol gerrit-no-reply at lists.osmocom.orgReview at https://gerrit.osmocom.org/5387 Set osmo-ggsn ipv6 link-local addr and enable ipv6 ctx activate test osmo-ggsn requires a link-local IPv6 address to be added to the tun interface, otherwise the apn will not be configured correctly and it won't be able to allocate addresses from the ipv6 pool later on. Some OS don't support autoconfiguring link-local IPv6 addresses when the interface is brought up (some linux versions are known to fail at it). This is the case for our Prod osmo-gsm-tester setup (running debian8 with kernel 3.16.51). Make sure we configure correctly the interface by forcing osmo-ggsn to set on the interface and use a specific IPv6 link-local address. This is done by using the "ipv6 link-local" vty cmd in osmo-ggsn. After this modification, we can re-enable ipv6 gprs context creation as it will work in Prod setup.
