What are the two configurations needed to set up EIGRP for IPv4?

1. router eigrp AS NUMBER; network NETWORK TO BE ADVERTISED

2. router eigrp AS NUMBER; passive-interface INTERFACE NUMBER

3. maximum-paths NUMBER; metric maximum-hops NUMBER

4. network NETWORK TO BE ADVERTISED; no-auto-summary

The correct answer is: router eigrp AS NUMBER; network NETWORK TO BE ADVERTISED

To effectively set up EIGRP (Enhanced Interior Gateway Routing Protocol) for IPv4, it is essential to configure both the EIGRP process and specify which networks will be included in the routing process. The first part of the correct answer involves initiating the EIGRP routing process with the command `router eigrp AS NUMBER`, where "AS" stands for Autonomous System. This establishes the EIGRP instance on the router and allows the router to participate in routing within the specified autonomous system. The second part involves using the `network NETWORK TO BE ADVERTISED` command, which guides the router on which interfaces should participate in the EIGRP process. This command will match the IP addresses configured on the router's interfaces to the network specified and ensure those networks are advertised to other EIGRP neighbors. In summary, both the initiation of the EIGRP process and the specific identification of networks to be advertised are crucial for establishing a functioning EIGRP environment. Thus, this choice captures the fundamental steps necessary for successfully configuring EIGRP for IPv4.
