Web28 Dec 2016 · Well, I guess that this SPT (Shortest Path Tree) is just a tree that has an edge from the source to each other node (cos if it isn't this way, it may contain cycles). Then, if … 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. Spanning tree also allows a network design to include backup links providing fault tolerance if … See more The need for the Spanning Tree Protocol (STP) arose because switches in local area networks (LANs) are often interconnected using redundant links to improve resilience should one connection fail. However, this connection … See more Before configuring STP, the network topology should be carefully planned. Basic configuration requires that STP be enabled on all switches in the LAN and the same version of STP chosen on each. The administrator may determine which switch will be the root … See more STP and RSTP do not segregate switch ports by VLAN. However, in Ethernet switched environments where multiple VLANs exist, it is often desirable to create multiple spanning … See more Spanning tree is an older protocol with a longer convergence time. Improper use or implementation can contribute to network disruptions. Blocking links is a crude approach to high availability and preventing loops. Modern networks can make use of all … See more The above rules describe one way of determining what spanning tree will be computed by the algorithm, but the rules as written require knowledge of the entire network. The … See more The first spanning tree protocol was invented in 1985 at the Digital Equipment Corporation by Radia Perlman. In 1990, the IEEE published the … See more IEEE 802.1aq, also known as Shortest Path Bridging (SPB), allows redundant links between switches to be active through multiple equal cost paths, and provides much larger layer-2 … See more

This is considered the SPT, or simply the “shortest path tree”. At this point traffic flows from the sender to the RP via the shortest path tree, and then from the RP down to the receiver via the shared ...

WebSource Tree – A source tree is a multicast distribution tree in which the source is the root and branches extend down the network to the receivers. When this tree is formed, it takes the shortest path possible through the network from the source to the tree’s leaves; thus, it is also known as the Shortest-Path Tree (SPT).

Optional parameter prefix-list can be use to control which groups to switch or not switch. If a group is PERMIT as per the PLIST, then the SPT switchover does not happen for it and if it is DENY, then the SPT switchover happens. swapna theatre thrissur
