3. Statistiques de surveillance RIB

3.1. Statistics Format

BMP Statistics Report messages carry statistics in TLV form (Stat Type, Stat Len, Stat Data). Statistics in this document are either Global Statistics or Per-AFI/SAFI Statistics. For Global Statistics, Stat Data is a single 64-bit unsigned integer Gauge and Stat Len MUST be 8. Each global statistic MUST appear only once in a BMP Statistics Report message.

For Per-AFI/SAFI Statistics, Stat Data is an 11-byte value: 2-byte AFI, 1-byte SAFI, and a 64-bit Gauge. Stat Len MUST be 11. For any per-AFI/SAFI Statistic, duplicate (AFI, SAFI) pairs MUST NOT appear in the same BMP Statistics Report message, and such statistics MUST NOT be included when there is no data for that AFI/SAFI.

If statistics apply to the Loc-RIB, the Peer Type field in the Per-Peer Header MUST be set to 3 (Loc-RIB Instance Peer) [RFC9069]. Otherwise, Peer Type is set as defined in Section 4.2 of [RFC7854]. A BMP implementation MUST ignore unrecognized Stat Types upon receipt.
