I guess you can do that and more with a linux based switch like cumulus and
pica8.
They allow you to do all sorts of things like that because they are open.

I’m asked to evaluate switching platforms that has different forwarding

Assuming these vendors give the same SDK and similar documentation/support,

I’m thinking,
Feedback about Cumulus has been positive :

Vendor X wants you to run their VNF (Router, Firewall or Whatever) and they

How would you calculate the cost of a network outage, specifically if its

Suppose that this could have been avoided by testing in a lab before
