What is the difference between interface topologies: Internet and Internal default route based?

[AlekzNet]

Hi All,

What is the difference between the following interface topologies:

- Internet
- Internal -> network defined by the routes (the default route is configured on this interface)

Any references to the documentation/SKs?

How is it working in the real life?

I'm asking because I discovered some strange behaviours...

Thank you in advance!

Did you ever end up opening TAC case?

Not yet, but I discussed it with the Diamond team. I will check $FWDIR/state/local/FW1/local.set first.

Cant recall ever checking that file myself, but may have a look in the lab tomorrow.

FWIW, below is what I see in my R81.20 jumbo 96 lab. Its same on the cluster as well. I just greped for internal and external.
