R80++ upgrade replacing topology definitions

[Vladimir]

Encountered this at one of my clients: In R77.30 they had multiple interfaces defined as "External" in topology.

I do not want to debate how and if it was wrong to do so, but the fact remains that the upgrade process changed those to "this network":

Yeah that definitely shouldn't happen.

I am not sure if client will be opening the case on this, as they have lived with this post-upgrade for a while.

Do you think you can kick it up to R&D to get their read on it for future references?

I still have the environment in my lab and may be able to get additional data if they need it or are unable to reproduce.

Thanks,

Vladimir
