EIGRP AS Number Definition: EIGRP AS Number: A unique identifier within the Enhanced Interior Gateway Routing Protocol (EIGRP) used to distinguish between different autonomous systems exchanging routing information.
EIGRP AS Number (Autonomous System Number) is a unique identifier used in Enhanced Interior Gateway Routing Protocol (EIGRP) to determine administrative boundaries within which routes are exchanged and kept separate. Each EIGRP router in the network is assigned an AS number to facilitate routing table maintenance and efficient path selection. AS numbers help routers distinguish between internal routes within the same AS and external routes learned from other ASs, enabling effective routing decisions in complex network environments.
