This is implemented by Arista in the feature that Yang linked to with the URL containing "fib-compression", but the actual command is better named: "ip fib compression redundant-specifics filter"I'll take my imagination boat from the dry docks and sail to 2035. Lot of people still run Jericho ANET, it is the new CAT6500 PFC3. DFZ won't fit it anymore without redundant-specifics. Are we at all concerned that someone in the DFZ advertises a minimum set of prefixes needed to force decompression and if we are, how do we protect from it, if we are not, why are we not?
I imagine that is not so easily done. I can only get away with announcing prefixes that I own, which for most people will limit the amount of damage you could do. For someone who has unfiltered access to announce any prefix, he can already today announce 16 million x /24 and crash just about any router out there.
