By default, VSTP uses the RSTP protocol as its core spanning-tree protocol, but usage of STP can be forced if the network includes old bridges. [26] More information about configuring VSTP on Juniper Networks switches was published in the official documentation. [27] Cisco also published a proprietary version of Rapid Spanning Tree Protocol.
The alternative is to have different logical switches, but then one of the used links will have to be blocked to ensure a loop-free topology (which can partially be overcome by using Multiple Spanning Tree or Cisco's proprietary per VLAN spanning tree. Spanning Tree Protocol is relatively slow in convergence, which can result in periods that ...
Common Internal Spanning Tree (CIST): Identifies regions in a network and administers the CIST root bridge for the network, for each region and for each spanning tree instance in each region. It's also the default spanning tree instance of MSTP so that any VLAN which isn't a member of a particular MSTI, will be a member of the CIST.
Unidirectional Link Detection (UDLD) is one of two major features (UDLD and loop guard) in Cisco Switches to prevent Layer 2 loops. Spanning-Tree Protocol (STP) resolves redundant physical topology into a loop-free, tree-like forwarding topology via blocking one or more ports.
Creation of malformed packets to verify whether a system processes a given protocol correctly; Didactical demonstrations as lab utility; Mausezahn allows sending an arbitrary sequence of bytes directly out of the network interface card. An integrated packet builder provides a simple command line interface for more complicated packets.
IEEE 802.1D is the Ethernet MAC bridges standard which includes bridging, Spanning Tree Protocol and others. It is standardized by the IEEE 802.1 working group. It includes details specific to linking many of the other 802 projects including the widely deployed 802.3 (Ethernet), 802.11 (Wireless LAN) and 802.16 (WiMax) standards.

A multicast address is a logical identifier for a group of hosts in a computer network that are available to process datagrams or frames intended to be multicast for a designated network service. Multicast addressing can be used in the link layer (layer 2 in the OSI model), such as Ethernet multicast, and at the internet layer (layer 3 for OSI ...
