1. Describe in detail all issues associated with Layer 2 loops and VTP. Which switches in your recommended design should be STP roots for which VLANs? Which STP mode do you recommend? Justify your selection.
a. The issues associated with Layer 2 loops are many but can be deterred in order to not have to encounter said problems. For starters, Layer 2 should have the following topology in order to function and maintain high stability: Spanning Tree Protocol (STP), Trunking (ISL/802.1q), Unidirectional Link Detection (UDLD), and EtherChannel. The requirement to support STP convergence should be avoided by design. A Layer 2 loop happens when more than one layer 2 forwarding path exists between two given switches. The outcome: a switch receives a broadcast frame sends it to all of its trunk ports and access ports making an amplification for the broadcast of the loop which in turn creates an indefinite loop within the network. The way to prevent this was stated above which was to have; Spanning Tree Protocol (STP), Trunking (ISL/802.1q), Unidirectional Link Detection (UDLD), and EtherChannel. …show more content…
Present best design practices to minimize Layer 2 loops and VTP.
