Router(config)# router eigrp autonomous_system_# This command will enable EIGRP routing protocol in router. We can use any ASN (Autonomous System Number) from 1 to 65,535. In order to become EIGRP neighbors this number must be same on all participates.

EIGRP Configuration Step by Step: a cisco packet tracer lab

1. Step1: Assign ip addresses on Router Interfaces as well as PC’s as mentioned in topology diagram.
2. Step 2: EIGRP configuration on R1:
3. Step 3: EIGRP Configuration on R2:
4. Step 4: EIGRP Troubleshooting command.
5. Check Routing Protocol on R1 Router for EIGRP:

EIGRP (Enhanced Interior Gateway Routing Protocol) is an enhanced distance vector protocol that uses Diffusing Update Algorithm (DUAL) for shortest path calculation. Basic configuration enables EIGRP routing process and tells EIGRP which interfaces to include in routing process locally.

Difference between OSPF and BGP. Border Gateway Protocol (BGP) Difference between Border Gateway Protocol (BGP) and Routing Information Protocol (RIP) EIGRP fundamentals. Features of Enhanced Interior Gateway Routing Protocol (EIGRP)

Configuring RIP requires the following steps:

1. Step 1 Enable the RIP routing process, which places you in router configuration mode via the Router#router rip command.
2. Step 2 Specify those networks that should be advertised using RIP via the Router(config-router)#network [network-number] command.

Configure the EIGRP for the IPv6 routing:

• Enable the IPv6 routing on a router.
• Assign the router ID of the each router.
• Enable the EIGRP for IPv6 routing on every router.
• Configure the EIGRP for IPv6 by using the AS 1 on a gigabit Ethernet and serial interfaces on a router.
• Determine a neighbor adjacency.

The scalability of the OSPF is higher than EIGRP because EIGRP is complicated and vendor-specific and incapable of migrating from one vendor to the other. Conversely, OSPF is an open standard and simple protocol through which the network can be scaled easily.

The IETF established OSPF as the standard for interior routing. Any router manufacturer can implement OSPF into its products, and most of them have. Is EIGRP Open Standard? EIGRP is a routing protocol that is proprietary to Cisco.

The router eigrp command entered in global configuration mode with autonomous-system-number argument creates an EIGRP routing instance. It is the first step in configuring EIGRP on a router as done here on R1: Enter configuration commands, one per line. End with CNTL/Z.

Use the address-family ipv4 command to configure IPv4 address family sessions in EIGRP and the address-family ipv6 command to configure IPv6 address family sessions in EIGRP. The following example shows how to enable an EIGRP authentication keychain:

It is recommended that you configure an autonomous-system number when the address-family is configured, either by entering the address-family command or the autonomous-system command. Use the router eigrp virtual-name command to configure an EIGRP named configuration.

To leave address-family configuration mode without removing the address family configuration, use the exit-address-family command. Use the router eigrp number command to configure an EIGRP autonomous-system (AS) configuration. In this configuration, EIGRP VPNs can be configured only under IPv4 address-family configuration mode.
