CCNA Training Course (3) -- Vlan VTP relay single-arm route generation Tree Protocol This is the third day of the CCNA training course. There are many knowledge points on this day, and the experiment content is gradually becoming more complicated.VLAN A vswitch separates the conflict domains and the broadcast domains.

subnet; the last IP address that can be assigned to the PC; The subnet's broadcast address.Two. The number of IP addresses required for each subnet is known1. Calculate the number of bits required for the host part (2 of the n is slightly larger than the number of IP, n is the host bit)2.32-host bits = = number of network bits3. Calculate subnet mask for subnets4. Reach the subnet segment (network address)5. The first IP address that can be assigned to a PC under each subnet; the last IP addres

. Trunk between switches2. All switches establish the same VLAN, (VTP)3. Each switch strokes the interface into the appropriate VLAN4. Configuring Layer 3 Information (IP)VtpVTP is used to unify the creation and deletion of VLAN information.VTP3 mode:Server: Can add, remove VLANs, learn VLAN information, transmit VLAN information to other peopleClient: Can not add, delete VLAN, can learn VLAN information from server, pass the learning information to othersTransparent: You can only add and delete
