Bpdu Header. Figure 2 shows the format of an ethernet frame. Contains the value 0000 for ieee 802.1d Stp_send_bpdu (p, &tcn_bpdu, sizeof tcn_bpdu);} static void: To prevent the delay when connecting hosts to a switch and during some topology changes, rapid stp was developed, which allows a switch port to rapidly transition into the forwarding state during these situations.

Rapid spanning tree protocol bpdus are received from a catalyst switch after connecting to a port not configured for portfast. The bridge priority making up the left most bits, is a value of 0 to 61440.the extended system id is a value of 1 to 4095 corresponding to the respective vlan participating in stp. Protocol identifier should always be 0x0000 for stp bpdu. The addition of the new fcs does not alter the original fcs that is contained within the encapsulated frame.

A switch sends bpdus using a unique source mac address from its origin port to a multicast address with destination mac (01:80:c2:00:00:00, or 01:00:0c:cc:cc:cd for cisco proprietary per vlan spanning tree). Bridge protocol data units (bpdus) are frames that contain information about the spanning tree protocol (stp). Bridge protocol data units (bpdus) are messages exchanged between the switches inside an interconnected redundant. The length or type field specifies the mac data length, and is followed by the llc header and bpdu header. The format of ieee 802.1d bridge protocol data unit (bpdu) is given below.
