Comment 13 for bug 1849392

It's a bit annoying that I can't find a rhyme or a specific pattern to the issue.

- Right now, if I restart all 3 l3_agent after marking a network as External, I can attach that network to a router and the ports will spawn properly.

I'm not sure if there is something wrong with the l3 agent when they first spawn but a restart after the initial setup seems to fix the issue.
