ECNM = Enterprise Composite Network Model


NAC = Network Access Control (NAC) and


IBNS = Identity Based Network Services (IBNS)

DUAL = Diffusing Update Algorithm (DUAL)

PDM = Protocol-dependent modules (PDMs) are responsible for network layer protocol-specific requirements. EIGRP supports IP,AppleTalk, and Novell NetWare. Each protocol has its own EIGRP module and operates independently from any of the others that may be running.


RTP = RTP is responsible for guaranteed ordered delivery and reception of EIGRP packets to all neighbors. RTP supports intermixed transmission of multicast and unicast packets. For efficiency, only certain EIGRP packets are transmitted reliably.


SRTT = (smoothed round-trip time): Average number of milliseconds it takes for an EIGRP packet to be sent to this neighbor and for the local router to receive an acknowledgment of that packet. This timer determines the retransmit interval, also known as the retransmission timeout (RTO).


RTO = (retransmission timeout): Amount of time, in milliseconds, that the router waits for an acknowledgment before retransmitting a reliable packet from the retransmission queue to a neighbor. If an EIGRP update, query, or reply is sent, a copy of the packet is queued. If the RTO expires before an acknowledgment is received, another copy of the queued packet is sent.


SIA = stuck in active (SIA)


LSDB = link-state database (LSDB)


SPF = Shortest Path First (SPF)
