Ericsson Technical Lead Interview Questions, Process, and Tips

MPLS ping is a tool used to test connectivity between two MPLS-enabled devices by sending ICMP echo requests.

• MPLS ping works by encapsulating ICMP echo requests within MPLS packets.

• It uses the MPLS label stack to route the packets through the network.

• The receiving device responds with an ICMP echo reply, allowing the sender to verify connectivity.

• MPLS ping is commonly used for troubleshooting MPLS networks and verifyin

MPLS is required for efficient and reliable data packet forwarding in complex networks.

• MPLS allows for traffic engineering, prioritization, and quality of service in networks.

• It provides better performance and reliability compared to traditional IP routing.

• MPLS is essential for connecting multiple locations in a secure and efficient manner.

• It simplifies network management and troubleshooting by creating virtual paths f

Routing process involves determining the optimal path for data packets to travel from source to destination.

• Routing is the process of selecting the best path for data packets to reach their destination.

• It involves analyzing network topology, traffic conditions, and routing protocols.

• Routing algorithms determine the most efficient path based on factors like hop count, bandwidth, latency, and cost.

• Routing tables are used...read more

Static route is a pre-configured path for network traffic to reach a specific destination.

• Static routes are manually configured by a network administrator.

• They are used to define a specific path for network traffic to follow.

• Static routes are commonly used in small networks with few routers.

• They are less flexible than dynamic routing protocols.

• Example: ip route 192.168.1.0 255.255.255.0 10.0.0.1
