Question

Explain EIGRP

Accepted Answer

EIGRP is an advanced routing protocol used in computer networks to efficiently exchange routing information.

EIGRP stands for Enhanced Interior Gateway Routing Protocol.
It is a Cisco proprietary protocol.
EIGRP uses a combination of distance vector and link-state routing protocols.
It supports both IPv4 and IPv6 networks.
EIGRP uses the Diffusing Update Algorithm (DUAL) to calculate the best path for routing.
It provides fast convergence and load balancing capabilities.
EIGRP uses multicast and unicast communication for exchanging routing updates.
It supports features like route summarization, authentication, and unequal-cost load balancing.
EIGRP uses bandwidth, delay, reliability, and MTU as metrics for path selection.
Example: EIGRP is commonly used in enterprise networks to ensure efficient and reliable routing.
