The Spanning Tree Protocol (STP) is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them.
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.
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
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.
Primary VLAN: Simply the original VLAN. This type of VLAN is used to forward frames downstream to all Secondary VLANs. Secondary VLAN: Secondary VLAN is configured with one of the following types: Isolated: Any switch ports associated with an Isolated VLAN can reach the primary VLAN, but not any other Secondary VLAN. In addition, hosts ...
Spanning-Tree Protocol (STP) resolves redundant physical topology into a loop-free, tree-like forwarding topology via blocking one or more ports. However, Unidirectional Link failure can cause "traffic blackholing" and loops in the Switch topology.
TRILL was designed as a successor to the Spanning Tree Protocol, both having been created by the same person, Radia Perlman. The catalyst for TRILL was an event at Beth Israel Deaconess Medical Center which began on 13 November 2002.
Perlman invented the spanning tree algorithm and protocol. While working as a consulting engineer at Digital Equipment Corporation (DEC) in 1984 she was tasked with developing a straightforward protocol that enabled network bridges to locate loops in a local area network (LAN). It was required that the protocol should use a constant amount of ...
