The network Command

In this article we will discuss The network Command, will make brief discussion on The network Command, In last article we discuss about EIGRP Router ID.

EIGRP router configuration mode allows for the configuration of the EIGRP routing protocol.

To enable EIGRP routing on an interface, use the network ipv4-network-address router configuration mode command. The ipv4-network-address is the classful network address for each directly connected network.

The network command has the same function as in all IGP routing protocols. The network command in EIGRP:

  • Enables any interface on this router that matches the network address in thenetwork router configuration mode command to send and receive EIGRP updates.
  • The network of the interfaces is included in EIGRP routing updates.

The network commands required to configure EIGRP on R1. In the figure, a single classful network statement, network, is used on R1 to include both interfaces in subnets and Notice that only the classful network address is used.

The network command used to enable EIGRP on R2’s interfaces for subnets and When EIGRP is configured on R2’s S0/0/0 interface, DUAL sends a notification message to the console stating that a neighbor adjacency with another EIGRP router on that interface has been established.

This new adjacency happens automatically because both R1 and R2 use the same autonomous system number (i.e., 1), and both routers now send updates on their interfaces in the network.

DUAL automatically generates the notification message because the eigrp log-neighbor-changes router configuration mode command is enabled by default. Specifically, the command helps verify neighbor adjacencies during configuration of EIGRP and displays any changes in EIGRP neighbor adjacencies, such as when an EIGRP adjacency has been added or removed.
