Hmmm…. I tried it on a Cisco ASR 9904,9001 and NCS-5502 (state of the art) devices:
767k routes took on a… ASR 9001: 4.5 minutes ASR 9904: 12 minutes NCS 5502: 17 minutes
Don’t why the smallest device is the fastest on *crazy*…
Maybe it can be disabled by default and a notice that enabling can increase the discovery time and slow down devices… something like “use at own risk”? ;)

This is huge.. NO, really very huge tables.
Discovery can fetch this table more than 10-20-30 mins. I already was test with such ability, many devices just did stop respond after try to fetch this table.
Klimek, Denismailto:DKlimek@Stadtwerke-Norderstedt.de 23 August 2018 at 13:55 Hi,
what is your opinion about extracting also the static configured routes from the device? Possible SNMP OID would be .1.3.6.1.2.1.4.24.7 We have the case that multiple prefixes are staticly configured and that we are able to fetch them in the Observium database for 3rd party purposes that we built around.
I know that pulling the routes from a device with a BGP full route takes a lot of time, but maybe it can be implemented into the discovery module instead of the poller. A way to ignore BGP or to exclude everything except static is not known so far…. From my side.
