6.3. Peer Down and Up Notifications 6.3. Peer Down and Up Notifications
PEER UP and DOWN notifications convey BGP peering session state to PEER UP and DOWN notifications convey BGP peering session state to
BMP receivers. The state is independent of whether or not route BMP receivers. The state is independent of whether or not route
monitoring or route mirroring messages will be sent for Adj-RIB-In, monitoring or route mirroring messages will be sent for Adj-RIB-In,
Adj-RIB-Out, or both. BMP receiver implementations SHOULD ignore the Adj-RIB-Out, or both. BMP receiver implementations SHOULD ignore the
O flag in PEER UP and DOWN notifications. BMP receiver O flag in PEER UP and DOWN notifications. BMP receiver
implementations MUST use the per-peer header O flag in route implementations MUST use the per-peer header O flag in route
