dpd msg
Function
The dpd msg command configures the payload sequence of DPD packets on the specified IKE peer.
The undo dpd msg command restores the default payload sequence of DPD packets on the specified IKE peer.
By default, the payload sequence of DPD packets on an IKE peer is seq-notify-hash.
Usage Guidelines
DPD packets carrying the notify payload and hash payload are exchanged bidirectionally. The notify payload sent by the initiator carries an R-U-THERE message equivalent to a Hello packet, and the notify payload sent by the responder carries an R-U-THERE-ACK message equivalent to an ACK packet.
The payload sequence of DPD packets sent by different devices may be different. IKE peers on both ends must send DPD packets with the same payload sequence; otherwise, DPD does not take effect. You can use the dpd msg command to set the same payload sequence of DPD packets on the two ends.
