This object is used in conjunction with the address-family specific bgpPeergrAfiSafiPrfxThreshClear to control when a bgpPeerAfiSafiPrfxThrshldClear trap is sent. This trap will only be sent if the number of prefixes associated with a peer in this peer group drops to this level AND a bgpPeerAfiSafiPrefixThreshold trap has previously been sent. In the case where bgpPeergrConfigThreshold is non-zero, a non-zero value of bgpPeergrPrfxThresholdClear is applied to the number of prefixes (totalled across all supported address families). Alternatively, in the case where bgpPeergrConfigThreshold is zero and per-AFI/SAFI configuration is being applied, separate values can be specified for each address family. To configure this, set bgpPeergrPrfxThresholdClear to zero and set bgpPeergrAfiSafiPrfxThreshClear for each address family for which a clear level is required.
