How to configure EIGRP in Cisco Packet Tracer?
EIGRP Configuration Step by Step: a cisco packet tracer lab
- Step1: Assign ip addresses on Router Interfaces as well as PC’s as mentioned in topology diagram.
- Step 2: EIGRP configuration on R1:
- Step 3: EIGRP Configuration on R2:
- Step 4: EIGRP Troubleshooting command.
- Check Routing Protocol on R1 Router for EIGRP:
What is wildcard mask in Eigrp?
The wildcard mask tells EIGRP to establish a relationship with EIGRP routers from interfaces that are part of network 172.16. 3.0/24 or 172.16. 4.0/24, but not 172.16. 5.0/24.
What is Eigrp in networking?
Enhanced Interior Gateway Routing Protocol (EIGRP) is a network protocol that enables routers to exchange information more efficiently than earlier network protocols, such as Interior Gateway Routing Protocol (IGRP) or Border Gateway Protocol (BGP).
What factors are used in the metric calculations for Eigrp by default?
Metric calculation is a critical component for any routing protocol. EIGRP uses multiple factors to calculate the metric for a path. Metric calculation uses bandwidth and delay by default but can include interface load and reliability, too.
What is the use of passive interface in EIGRP?
Passive Interfaces Passive EIGRP interfaces do not send out or process EIGRP hellos, which prevents EIGRP from forming adjacencies on that interface. To configure an EIGRP interface as passive, you use the command passive-interface interface-id under the EIGRP process for classic configuration.
Why EIGRP is called Advanced distance vector?
So the most correct way to describe EIGRP is indeed as an Advanced Distance Vector Routing Protocol. It uses the Diffusing Update Algorithm, (DUAL) which is different to the Bellman-Ford algorithm used by RIP and different to Dijkstra’s Shortest Path First algorithm used by OSPF and IS-IS.
Why does EIGRP use lowest bandwidth?
The path with the lowest bandwidth is the choking point of the entire path. EIGRP use the lowest bandwidth in the path for calculating the FD of the path, it does not necessarily means that it will use the path with the lowest bandwidth. Hi!
How does EIGRP measure delay?
The delay value used in the EIGRP metric calculation is the delay in 10’s of microseconds. So to calculate the Delay value, simply divide the DLY in the show interface command by 10. The Delay Value of 10 will be plugged into our simplified EIGRP Metric formula we derived earlier.
What metric does EIGRP use?
EIGRP determines the value of the path using five metrics: bandwidth, load, delay, reliability and MTU.
What are the types of tables used in EIGRP?
EIGRP uses three tables: the neighbor table, the topology table, and the IP routing table. The neighbor table keeps state information regarding neighbors, and is displayed using the show ip eigrp neighbors command. EIGRP Update messages fill the routers’ EIGRP topology tables.
What is a 30 network?
The /30 signifies that the network part of the address is 30 bits long, leaving 2 bits for the host part which equals 4 available addresses.
