WebThe Spanning Tree Protocol (STP) is a network protocol that is used to eliminate bridge loops in Ethernet LANs. STP prevents network loops and associated network outage by blocking redundant links or paths. The redundant paths can be used to keep the network operational if the primary link fails.

WebThe gold standard for preventing switching loops is the Spanning Tree Protocol (STP). It works by creating a group of switches that exchange information via special frames called bridge protocol data units (BPDUs) to create and maintain a loop-free topology. WebSplit horizon is one of the features of distance vector routing protocols that prevents routing loops. This feature prevents a router from advertising a route back onto the interface from which it was learned. Consider the following network topology: Router R1 has a route to the subnet 10.0.1.0/24 that is advertised to router R2 by using RIP. north face puff
