Q1. What is stuck switching?
Ans. 
Stuck switching refers to a situation where a network switch is unable to forward traffic due to a malfunction or configuration issue.
• Stuck switching can occur when a switch's forwarding table becomes corrupted or when there is a hardware failure.

• It can also happen if there is a loop in the network causing broadcast storms.

• Troubleshooting stuck switching involves checking the switch's configuration, monitoring network ...read more

Q2. What is bgp path selection process
Ans. 
BGP path selection process determines the best path for routing based on various attributes.
• BGP selects the path with the highest weight attribute first

• If weights are the same, BGP looks at the local preference attribute

• Next, BGP considers the AS path length

• BGP then checks the origin code attribute

• After that, BGP looks at the MED (Multi-Exit Discriminator) attribute

• If all else is equal, BGP chooses the path with the lo...read more

Q3. What is stub area
Ans. 
A stub area is an OSPF area that does not contain external routes.
• Stub areas reduce the amount of routing information exchanged within an OSPF network.

• Stub areas use a default route to reach external networks.

• Stub areas are commonly used to reduce the size of the OSPF database and improve network performance.

Q4. What is stp? how to work.
Ans. 
STP stands for Spanning Tree Protocol, used in network environments to prevent loops and ensure redundant paths are utilized efficiently.
• STP is a network protocol used to prevent loops in Ethernet networks.

• It works by selecting a single path for data traffic while blocking redundant paths.

• STP elects a root bridge and calculates the shortest path to each network segment.

• If a link fails, STP recalculates the network topo...read more

Q2. Routers switch configuration and commands
Ans. 
Routers switch configuration and commands involve setting up and managing network devices for efficient data routing.
• Routers use commands like 'show ip route' to display routing table information

• Configuration involves setting up IP addresses, subnet masks, and default gateways

• Commands like 'show interfaces' can display interface status and configuration details

Q1. Routing tables in bgp and explain
Ans. 
BGP routing tables store information about routes to different networks and the best path to reach them.
• BGP uses a path-vector routing protocol to determine the best path for a packet to reach its destination.

• BGP routing tables contain information about the network prefixes, the next hop to reach them, and the path attributes that determine the best path.

• BGP routers exchange routing information with their neighbors to ...read more

Q3. What is nat and port number that can be used
Ans. 
NAT is a technique used to map private IP addresses to public IP addresses. Port numbers are used to identify specific applications.
• NAT stands for Network Address Translation

• It is used to allow devices with private IP addresses to access the internet using a public IP address

• Port numbers are used to identify specific applications or services

• Common port numbers include 80 for HTTP, 443 for HTTPS, and 22 for SSH

Q4. If neither the port range in source NAT pools nor the default port range are configured, the default single port range is 1024 through 63,487.
Ans. 
Default single port range when neither port range in source NAT pools nor default port range are configured.
• When neither port range in source NAT pools nor default port range are configured, the default single port range is 1024 through 63,487.

• This range is used for outbound traffic initiated by the device.

• It is important to configure the port range to avoid conflicts with other devices on the network.

• For example, if m...read more

Q5. What is mss in tcp explain
Ans. 
MSS in TCP refers to the maximum segment size, which is the largest amount of data that can be sent in a single TCP segment.
• MSS is negotiated during the TCP three-way handshake

• It is determined by the maximum transmission unit (MTU) of the network

• MSS can be adjusted by the sender or receiver using TCP options

• A smaller MSS can help prevent fragmentation and improve network performance
