Hello all,
I recently upgraded a vyos router from 1.2.4 to the latest 1.4 nightly build from this morning 2022-03-19
Everything worked, including a site-to-site wireguard vpn. The only exception was OSPF. I have a main segment with all kinds of routers on it that keep each other updated via ospf (some Ubiquiti EdgeRouters, a couple vyos, Juniper, Cisco, etc) and I have all of these set to authenticate with a simple plaintext password in OSPF. As soon as the vyos upgrade happened, it stopped communicating via ospf to all the other routers.
So I went through some of the other routers and turned off plaintext auth, and my new nightly vyos immediately started sending and receiving routes - even though it had plaintext auth still active in the config. So it looks like it is just ignoring the plaintext auth settings and trying to communicate without it.
