> Addition of first member to the bridge is quite different from addition o=
f others. Why do you think it interferes with traffic flow every time?

Mostly because I could not find any documentation regarding this so all I h=
ad
to go by was what I observed and it never occurred to me to try a second or
third interface after seeing the problem with the first.

The actions/commands in the initial bug report, along with a diagram of the
setup, and hardware specifications.

The ill effect is losing network connectivity for a few seconds, for a serv=
er
that can be quite problematic.

Perhaps I'm approaching this all wrong and trying to squeeze s square peg
through a round hole. Are bridge/epairs the wrong tools for vnet jails, is
there a better alternative?
