stumbled across this statement 'bgp network import-check exact' in a quagga config looking at a Cumulus example repository (here: https://github.com/CumulusNetworks/cldemo-config-routing/blob/master/bgp-numbered/leaf01/Quagga.conf
can't seem to find exactly what this does. Based on some documentation I -think- its purpose is to make sure that Prefixes matched by a BGP network statement are Local to the devices before importing into the BGP RIB? Suggesting the default behavior would be to to match, say, a static route or even OSPF-learned route from the RIB and bring it into the BGP RIB?
Haven't been using this statement in my lab tests prior to production rollout and so far things seem ok, curious if its considered a best practice or not to leverage this function, or if I'm even understanding its use correctly
