for junos, i build the prefix list externally and push config. sad to say, the code is so old ('90s) that it's pearl and uses `peval`. i should fix but (copious spare time) == 0.
Spare time must be > 0 if you're willing to wait for peval to finish ;-)
originally i tried to also build and push for cisco ios classic, but it died in the push. breathe on the router and it reset bgp sessions. i gather from heas that things are better these years.
Better, but not good (or even tolerable). There is a reason I didn't provide an example of doing this kind of thing on IOS classic/XE.
i guess i really should have a go at doing it for arcos, but ...
The thing that EOS and JUNOS have in common that allows this to work is a mechanism to store config state outside the main "running config". In JUNOS that's the ephemeral DBs, in EOS they call it "URL based import" for as-path and prefix lists. If ArcOS doesn't already have something similar, I'd get it on the list. Cheers, Ben
