STP prevents switching loops by creating a loop-free logical topology and blocking redundant paths.
STP creates a loop-free logical topology by placing certain ports in blocking state to prevent loops.
RSTP (Rapid Spanning Tree Protocol) improves upon STP by reducing convergence time and introducing alternate port roles.
MSTP (Multiple Spanning Tree Protocol) improves upon STP by allowing for multiple spanning tree instan
Policy-based routing (PBR) allows for routing decisions based on defined policies rather than traditional routing protocols.
PBR allows network administrators to define specific criteria for routing decisions, such as source IP address, application type, or packet size.
PBR can be used to route traffic over specific paths based on policies set by the administrator, such as sending VoIP traffic over a low-latency link.
PBR...
BGP Path Selection process determines the best path based on various attributes.
BGP routers receive multiple paths to a destination network from different peers.
BGP uses a set of criteria to select the best path, such as AS path length, local preference, origin code, etc.
The path with the highest weight is chosen as the best path and used for routing.
If the weight is the same, BGP compares the local preference, then th...
OSPF LSA types include Router LSA, Network LSA, Summary LSA, and ASBR Summary LSA, each serving a specific purpose in building the OSPF database.
Router LSA: Generated by each router to describe its directly connected links.
Network LSA: Generated by DR to describe the network and its attached routers.
Summary LSA: Generated by ABR to advertise routes between areas.
ASBR Summary LSA: Generated by ASBR to advertise external...
EIGRP's DUAL algorithm is a loop-free routing algorithm used for route computation and convergence in EIGRP networks.
DUAL algorithm ensures loop-free paths by maintaining a topology table with feasible successors and successors for each destination.
When a link or route fails, DUAL algorithm calculates a new loop-free path to the destination using feasible successors.
DUAL algorithm minimizes convergence time by quickly ...

Load sharing in BGP involves distributing traffic across multiple paths to optimize network performance.
BGP allows for multiple paths to a destination to be advertised and stored in the routing table
Load sharing can be achieved through equal cost multi-path (ECMP) or unequal cost multi-path (UCMP)
ECMP distributes traffic evenly across multiple paths with the same cost
UCMP distributes traffic across paths with different...

A network is a group of interconnected devices that communicate with each other. An IP address is a unique identifier assigned to each device on a network.
A network is a collection of devices such as computers, printers, and servers that are connected to each other.
An IP address is a unique identifier assigned to each device on a network to enable communication between devices.
The range of an IP address is determined b...
Answering questions related to network administration including subnetting, host configuration, and routing protocols.
Subnetting involves dividing a network into smaller subnetworks for better management and security.
Host configuration refers to the setup and management of individual devices on a network.
Standard and extended ACLs are used to control access to network resources based on IP addresses.
Routing protocols l...
OSI stands for Open Systems Interconnection. It is a conceptual model that describes how data is transmitted over a network.
OSI model has 7 layers, each with a specific function
The layers are: Physical, Data Link, Network, Transport, Session, Presentation, and Application
Each layer communicates with the layer above and below it
The model helps ensure interoperability between different network devices and software
Example...
2 out of 5 pool members are down in F5 bigip load balancer.
The load balancer is currently using the 3 available pool members to distribute traffic.
The 2 down pool members need to be fixed or removed from the pool to prevent traffic from being directed to them.
The load balancer should be monitored to ensure that it is functioning properly and distributing traffic evenly.
If necessary, additional pool members can be added...
