z In the beginning In the beginning, each switch regards itself as the root, and generates a configuration BPDU for each port on it as a root, with the root path cost being 0, the ID of the designated bridge being that of the switch, and the designated port being itself.
RSTP (R apid S p annin g T ree Pro tocol) , evo lved f rom t he 802 .1D STP standard, enable Ethernet ports to transit their states rapidl y . The premises for the port in the RSTP to transit its state rapidly are as follows.
Figure 7-2 Basic MSTP diagram ¾ MSTP MSTP divides a network into several MST r egions. The CST is generat ed betwee n these MST regions, and multiple spanning trees can be gener ated in each MST region. Each spanning tree is called an instance. As well as STP , MSTP us es BPDUs to generate sp anning tree.
Figure 7-3 Port roles The S panning T ree module is mainly for spanning tree configuration of the switch, including four submenus: STP Config , Port Config , MSTP Inst ance and STP Security . 7.1 STP Config The STP Config function, for global configuration of spanning trees on the switch, can be implemented on STP Config and STP Summary pages.

Chapter 8 Multicast ¾ Multicast Overview In the network, packet s are sent in three modes: unicast, broadcas t and multicast. In unicast, the source server sends separate copy information to each receiver . When a large number of users require this information, the serv er must send many pieces of info rmation with the same content to the users.
¾ Multicast Address 1. Multicast IP Address: As specified by IANA (Internet Assigned Numbers Authority), Class D IP addresses are used as destination addresses of multic ast packets. The multicast IP addresses range from 224.0.0.0~239.255.255.255. The following table displays the range and description of several special multicast IP addresses.
¾ IGMP Snooping In the network, the hosts apply to the near Router for joining (leaving) a multicast group by sending IGMP (Internet Group Management Protocol) me ssages. When the up-str eam device forwards down the multicast data, the switch is responsible for sending them to the hosts.
3. IGMP Leave Message The host, running IGMPv1, does not send IGMP l eave message when leaving a multicast group, as a result, the switch cannot get the leave info rmation of the host momentarily .
