How to configure PVSTP operation: root bridge elections and spanning tree protocol IP addressing (IPv4 & IPv6)

Certification: CCNA Routing and Switching - Cisco Certified Network Associate (CCNA) Routing and Switching

The spanning tree protocol is defined as a network protocol that take part in preventing broadcast radiation and bridge loops from taking place mostly in the Ethernet local area network and ensures that there is an appropriate network design to provide the required backup paths if either of them fails when there is transmission of network and other data packets. It was first introduced in the IEEE 802 to replace the RSTP and aids in the creation of layer two bridges disabling the links that are not part of the system. The spanning tree protocol is usually based on an algorithm and therefore there are certain rules to be applied in order to determine a suitable spanning tree protocol for the appropriate IP address.

Identifying the spanning tree protocol

The first rule is to select an appropriate root bridge from a number of available blocks that are usually presented in numbered blocks and lettered clouds that usually present the available network segments. In the contents there is also the bridge that is usually presented as the smallest bridge. The second rule is to determine the least cost path to the root bridge of that particular IP address in this case it can be either the IPv4 or the IPv6 address. The PVSTP will always consider its property that traverses the message that is always connected to the root bridge that will traverse the least possible path among all the available roots in the device. To be able to make this method more efficient, the administrator allows the administrator to configure its settings so that the cheapest path can be used. The root bridge on the other hand determines the possible cost from the available sources and this is an advantage when it comes to IP addressing since the data packets needed to be transmitted will be quite sufficient hence reducing the possibility of collisions from occurring. In addition the root bridge connected to this network segment forms a designated port to be used by the two IP addresses.

The effect of this rule is that all the other root ports that are active yet they are not of any use are automatically disabled and this saves on cost of operation and also of obtaining and using a certain network. There is also the idea of further modifications in the case where there was an occurrence of any type of ties that resulted from transmission of the network through the ports on the same local area network segment. To reverse this problem the second option is to use a single bridge by attaching it to a number of ports this will result to the use of the same cost that is always the least as compared to using two different bridges. The other option is breaking the ties that were formed in the process by the multiple paths and opting for only one path especially that which uses the lower bridge because as earlier seen the lower bridge is the most efficient one. In case there are designated ports to be used by the IP addresses one is advised to break the ties as soon as detected and connecting them to the lowest LAN segment then set up a forwarding mode that will create the final tie breaker. IN most sections there are two lower bridges to be chosen from and this is an advantage since one address two different IP addresses at the same without facing any problem and in addition there will be no collisions of the hosts that are identical and working together in the IPv4 addressing and IPv6 this idea enables its performance to be more efficient without facing any difficulties.

Sequence to use in IP addressing

First by using the lowest root bridge identity which determines the most suitable root bridge, determining the least possible cost to the root bridge from the available options and this is easily done by using the upstream switch that in most cases is always the favored one with the least possible cost, then by using the sender bridge that appears to be the lowest this will help to easily have the appropriate ties and either use the multiple ones that are usually the best choice and gives the option of using the same cost regardless of the number of ports connected to them during operation. The other requirement is the use of the lowest sender port identity and this is to enable the IP address to connect more efficiently to the channels that are not directly connected to the Ethernet network and it further gives two more options the bridge identity that has a priority, a locally assigned address and an identity extension and default bridge priority the port identity on the other hand has a priority with four bits, an  interface number and its default priority number happens to be one hundred and twenty eight.

The bridge protocol units

Its main function is to identify and exchange information on root path costs and the identity bridges the MAC address that is common in the IP addresses. To ensure that there is adequate servicing the BPDU is usually configured so as to match the required IP address and a topology change notification that are used to change the network criteria in each internet protocol. They are usually interchanged to enable the switches to be connected to several ports. This replacement enhances the number of available ports in the case when the host and the server relate with each other.

The units enable the IP address to carry out the following roles, backing up during addressing, forwarding of messages and detection of any possible collisions and lastly discarding any unwanted information.
