From 6964ba4a984691d79cff77506a37d0fa222a5599 Mon Sep 17 00:00:00 2001 From: Julia Kreger Date: Mon, 25 Apr 2022 08:48:20 -0700 Subject: [PATCH] Set public bridge up for v6 only configurations A long time ago, Ironic's IPv6 only job started to fail working with errors indicated the host was unreacable. Turns out, this was because the $ext_gw_interface was not being set to up, and thus could be found in a Down state, and thus the kernel would not accept routes for it. Adds an explicit step to turn up the public bridge, much as done in the IPv4 router plugin code which would also be executed in 4+6. That being said, Ironic's CI jobs are very intentionally IPv6 only to ensure that we have no chances of v4 addressing getting used at any point in time. This should allow Ironic to return it's IPv6 only CI job back to the normal check queue, once a ironic plugin issue has been resolved which was introduced while it was removed.
