WebC. The switch that will share the VLAN information must be configured as the root bridge. D. The switches must be configured to use the same VTP version. E. The switches must be configured to use the same STP version. F. The switches must be configured to use the same type of ID tagging. G. The switches must be connected over VLAN trunks. WebFeb 6, 2024 · A bridge is a way to connect two Ethernet segments together in a protocol independent way. Packets are forwarded based on Ethernet address, rather than IP address (like a router). Since forwarding is done at Layer 2, all protocols can go transparently through a bridge. The Linux bridge code implements a subset of the ANSI/IEEE 802.1d …
WebBridge Protocol Data Units (BPDUs) are messages exchanged between the switches inside an interconnected redundant Local Area Network (LAN). Bridge Protocol Data Units (BPDUs) frames contain information regarding the Switch ID, originating switch port, MAC address, switch port priority, switch port cost etc. WebTopology change Bridge Protocol Data Units (BPDUs) are sent after a topology change has been detected to indicate that the Spanning Tree Protocol (STP) algorithm should be initiated. The format of IEEE 802.1D Bridge Protocol Data Unit (BPDU) is given below. • Protocol ID (2 bytes): Contains the value 0000 for IEEE 802.1D

WebAug 9, 2024 · It is always calculated from the Root Bridge. Default path cost at the Root Bridge is 0. BPDU contains the path cost information. When the Root Bridge advertises BPDU out from its interfaces, it sets the path cost to 0. The switch which receives this BPDU increments the path cost by adding the port cost value of the port on which the BPDU …
