Mahindra Accelo Interview Questions and Answers

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 is often used in scenarios where traditional routing prot...read more

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 routes into OSPF domain.

• Different LSAs contribute to OSPF...read more

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 recalculating routes based on the new network topology.

• EIG...read more

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 instances, each with its own root bridge.

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 the AS path length, and so on.

• BGP can also use route reflect...read more
