Q2. What are the outine protocol and explain BGP, EIGRP and ISIS.
Ans. 
BGP, EIGRP, and ISIS are routing protocols used in networking.
• BGP (Border Gateway Protocol) is used for routing between different autonomous systems.

• EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco proprietary protocol used for routing within a single autonomous system.

Q3. What is VPN and VLAN
Ans. 
VPN is a secure connection between two networks while VLAN is a logical grouping of devices on a network.
• VPN stands for Virtual Private Network and is used to securely connect two networks over the internet.

• VPN uses encryption to protect data transmitted over the network.

• VLAN stands for Virtual Local Area Network and is used to logically group devices on a network.

• VLANs can be used to separate traffic on a network for ...read more

Q1. What is OSI and TCP/IP model
Ans. 
OSI and TCP/IP models are reference models used to describe how data is transmitted over a network.
• OSI model has 7 layers, while TCP/IP model has 4 layers

• OSI model is theoretical, while TCP/IP model is practical

• OSI model is used for teaching and understanding networking concepts, while TCP/IP model is used for actual implementation

• Examples of layers in OSI model: Physical, Data Link, Network, Transport, Session, Presen...read more

Q2. What is MPLS, MP-VPN, MPLS-TE.
Ans. 
MPLS is a protocol for efficient data transfer, MP-VPN is a VPN service using MPLS, and MPLS-TE is a traffic engineering extension of MPLS.
• MPLS stands for Multiprotocol Label Switching and is used to efficiently route data packets through a network.

• MP-VPN is a VPN service that uses MPLS to securely connect multiple sites or users to a private network.

Q3. What is MTU and how to find the MTU size for CE/PE
Ans. 
MTU stands for Maximum Transmission Unit. It is the largest size of data packet that can be transmitted over a network.
• MTU is measured in bytes.

• The default MTU size for Ethernet is 1500 bytes.

• To find the MTU size for CE/PE, you can use the ping command with the -f option to set the Do Not Fragment (DNF) bit and gradually increase the packet size until you receive a 'packet needs to be fragmented but DF set' message.

• Ano...read more

Q4. What are BGP attributes and how can we identify
Ans. 
BGP attributes are characteristics used to determine the best path for routing traffic between networks.
• BGP attributes include: AS Path, Next Hop, Local Preference, Multi-Exit Discriminator (MED), Weight, and Origin.

• AS Path identifies the sequence of autonomous systems that the route has passed through.

• Next Hop identifies the IP address of the next router in the path.

• Local Preference is used to indicate the preferred p...read more
