This object determines the action taken when any neighbor in this group's learned route count hits the group's csBgpNbrGroupMaxPfx limit, defaulting to shutdown if the limit is set but this type isn't explicitly configured. Administrators choose this behavior to consistently protect against any single misbehaving peer within a group of otherwise similar customers. For example, an engineer leaves csBgpNbrGroupMaxPfxType at its default shutdown setting for a group of untrusted external peers, ensuring any one of them exceeding its prefix limit gets disconnected automatically.
