The delay to enforce in between a TCP connection with peers in this peer group becoming established and a BGP Open message being sent. If this delay is zero, then no delay will be injected, and a BGP Open message will be sent as soon as the TCP connection allows it. This field can be changed at any time. However, if a peer is configured to use the peer group field and the field is changed while the peer is active, depending on the setting of the bgpPeergrResetPeerOnCfgChange field, the peer session may either be immediately reset, or the configuration change is not applied until the peer session is restarted.
