yes, something like that would be necessary.  I haven't used vpls PE
redundancy myself, so can't confirm whether this configuration will
actually work correctly, but bgp autodiscovery will definitely not work.
 Also, you should think long and hard about whether vpls (with or
without redundancy) is a feature that you want to use in production. It
has a lot of failure modes which can lead to catastrophic network failure.

Also, asciiflow.com is really useful for creating diagrams.
