This object sets the percentage of csBgpNbrMaxPfx at which a warning is generated as the route count learned specifically from this peer approaches its individual limit. Administrators use it to get early warning for a specific neighbor before that neighbor's session gets torn down for exceeding its prefix limit. For example, setting csBgpNbrMaxPfxThreshold to 90 for a large customer peer gives the admin a heads-up once that neighbor's advertised routes reach 90 percent of its configured csBgpNbrMaxPfx, before the connection is dropped.
