This object sets the percentage of csBgpGenMaxPfx at which a warning message is generated as the total learned route count from all peers approaches the configured maximum. Administrators use it to get advance warning before actually hitting the hard prefix limit, giving time to react before routes start being discarded. For example, setting csBgpGenMaxPfxThreshold to 80 causes a warning once this virtual router has learned 80 percent of the configured csBgpGenMaxPfx routes, prompting the admin to investigate before the limit is reached.
