Adding bridge member fails

I am trying to create a new bridge interface, but when I add a member, it fails.

Using the bridge to pass layer 2 traffic from one interface to another.

Here is the addition:

+bridge br0 {
+    member {
+        interface eth2:1000 {
+        }
+    }

And the error:

vyos@vyos# commit
[ interfaces bridge br0 ]
VyOS had an issue completing a command.

Replace eth2:1000 to eth2.1000

I cannot believe I completely missed that.

Commit is working now and so is the bridge…

I actually have this working with a manual install of ZeroTier with the understanding that upgrades may break it and I have to reconfigure some things.
