EIGRP Protocol Configuration Steps
EIGRP (Enhanced Interior Gateway Routing Protocol) is a popular routing protocol used in enterprise networks. It is a hybrid routing protocol that combines the characteristics of both distance-vector and link-state routing protocols. EIGRP provides fast convergence, efficient use of bandwidth, and support for variable-length subnet masks (VLSMs), making it a popular choice for large-scale networks.
In this article, we will discuss the steps involved in configuring EIGRP on a Cisco router.
Step 1: Enable EIGRP Routing on the Router
The first step in configuring EIGRP is to enable it on the router. This can be done using the "router eigrp [ASN]" command, where [ASN] is the autonomous system number. The autonomous system number is a unique identifier that is used to distinguish EIGRP domains.
Step 2: Define the Networks to be Advertised
After enabling EIGRP, the next step is to define the networks that will be advertised by the router. This is done using the "network [IP_ADDRESS]" command, where [IP_ADDRESS] is the IP address of the network that will be advertised.
Step 3: Configure EIGRP Metrics
EIGRP uses a metric to determine the best path to a destination network. The default metric used by EIGRP is a composite metric that takes into account bandwidth, delay, reliability, and load. The metric can be configured using the "metric weights [BW] [DLY] [REL] [LOAD]" command, where [BW], [DLY], [REL], and [LOAD] represent the weights assigned to bandwidth, delay, reliability, and load, respectively.
Step 4: Verify EIGRP Configuration
Once the configuration is complete, it is important to verify that EIGRP is working as expected. This can be done using the "show ip protocols" command, which displays information about the active routing protocols on the router. The "show ip route" command can also be used to verify that the EIGRP routes are being advertised and used by the router.
In conclusion, configuring EIGRP on a Cisco router is a straightforward process that involves enabling EIGRP, defining the networks to be advertised, configuring the EIGRP metrics, and verifying the configuration. By following these steps, administrators can easily configure EIGRP on their networks and take advantage of its advanced features and benefits
EIGRP Configuration Commands packet tracer
Here are some common static EIGRP configuration commands:
router eigrp [ASN]: Enables EIGRP and defines the autonomous system number
network [network address] [wildcard mask]: Specifies the networks that will participate in EIGRP.
passive-interface [interface]: Configures an interface as passive, meaning it will not send or receive EIGRP updates.
no passive-interface [interface]: Removes the passive status of an interface.
variance [multiplier]: Specifies the maximum allowable variance of metric values for unequal cost load balancing.
6. timers active-time [seconds]: Specifies the active time for a route in the routing table.
distance eigrp [internal-distance] [external-distance]: Changes the administrative distance for internal and external EIGRP routes.
EIGRP Protocol Importance
EIGRP (Enhanced Interior Gateway Routing Protocol) is an advanced routing protocol that is used by routers to exchange routing information within an autonomous system (AS) in a network. EIGRP provides fast convergence, low network overhead, and efficient use of bandwidth. It supports multiple network layer protocols and uses advanced algorithms to calculate the best path for data transmission. This makes EIGRP an important protocol for large and complex network environments, providing robust and scalable routing solutions.
