To enable EIGRP on specified interfaces, which command is used?

The command to enable EIGRP (Enhanced Interior Gateway Routing Protocol) on specified interfaces is structured in a way that allows the router to identify which interfaces to apply EIGRP to based on the IP addresses configured on those interfaces. By using the command "network ip-address [wildcard-mask]," the network statement specifies the range of IP addresses for which EIGRP will be activated.

This command provides the necessary parameters for EIGRP to recognize interfaces that fall within the specified network. The IP address refers to the network address, while the wildcard mask allows for flexibility in defining which addresses in that network should be included. This means that any interface that has an IP address matching the network plus any addresses defined by the wildcard mask will have EIGRP enabled.

This method of configuration is essential for ensuring that EIGRP only runs on relevant interfaces, effectively managing routing protocols and simplifying the routing process within the network.
