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.

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.

i guess i really should have a go at doing it for arcos, but ...
