Level3 has a very specific/finicky RPSL based router configuration tool. So specific in fact if you have your route objects in RADB and include customer objects from ALTDB the ALTDB objects will be filtered. If you are having this problem – here’s the secret, Level3 needs to add additional sources to their search path, enable recurseok and warnonly. Example below:
import policy:-le=32 RADB::AS-PHYBER -searchpath=RADB;ALTDB -recurseok -warnonly
