The network command has the same function as in all IGP routing protocols. It enables any interface on this router that matches the network address. It enables EIGRP routing on an interface, using the command in router configuration mode and enter the classful network address for each directly connected network. The command syntax is as… Read more
EIGRP router ID is a 32-bit unique identifier identifying the router in the EIGRP domain. The router ID (RID) is represented in the same way as the IPv4 address. The router ID is used both in EIGRP and OSPF, while the role of the router ID is more significant in OSPF. EIGRP automatically selects the
The “router” command in global configuration mode is an important command for start configuration of any dynamic routing protocol. The topology displayed in Figure 1 is used to configure and demonstrate the EIGRP routing protocol. Figure 2 (marked with a red triangle) illustrates the “router ?” with question marks to demonstrate the list of dynamic
Autonomous system numbers (ASNs) is a unique identifier that is globally available and allows its autonomous system to exchange routing information with other systems. An Internet Assigned Numbers Authority (IANA) globally assigned autonomous system is a group of networks under the administrative control of a single body that presents a common routing policy to the

EIGRP uses 5 different types of packet in communication with its neighbours. EIGRP packets are sent with reliable or unreliable delivery and can be sent as a unicast, multicast, or sometimes both. EIGRP packet types are also called EIGRP packet format or EIGRP messages. The details of the EIGRP packets are the following: EIGRP Hello
EIGRP uses a Reliable Transport Protocol (RTP) to deliver and receive EIGRP packets instead of TCP and UDP. Reliability is a key feature of EIGRP, and it is designed to enable fast update delivery and data reception tracking.EIGRP was designed as a network-layer independent routing protocol. This allows EIGRP to be used for protocols other
EIGRP uses a protocol-dependent module (PDM) for routing with several different protocols including IPv4 and IPv6. EIGRP also used PDMs to route Novell’s IPX and Apple Computer’s AppleTalk network-layer protocols. The protocol-dependent module (PDM) is also responsible for carrying information from the routing table to the topology table. protocol-dependent module (PDM) is also responsible for
Enhanced Interior Gateway Routing Protocol (EIGRP) was introduced as a distance-vector routing protocol in 1992. It was originally designed to work as a Cisco proprietary protocol on Cisco devices only. In 2013, Enhanced Interior Gateway Routing Protocol became a multi-vendor routing protocol. Enhanced Interior Gateway Routing Protocol is an advanced version of IGRP that lets
