A set of bit flags, used together with bgpPeerConfigUsage2 and bgpPeerConfigUsage3, which control where the peer picks up its configuration from. A bit flag exists for a subset of the peer's configuration fields which can also be configured on a peer group. More specifically, this subset consists of the fields in bgpPeerTable (or bgpPeerAfiSafiTable) which have a corresponding entry in bgpPeergrTable (or bgpPeergrAfiSafiTable). For this subset of fields, the peer should use the peer configuration value if the bit flag is unset and should use the peer group configuration value if the bit flag is set. For a specific peer AFI/SAFI, this flag might be overridden. For details, see bgpPeerAfiSafiConfigFromGr.
