Unit 1: Network Infrastructure
This will allow you to demonstrate your networking skills, knowledge, and abilities, with a focus on enterprise-level switching, routing, and multicast components that support cross-platform (inter)operability and integration with the most recent software-defined technologies.
EIGRP Named Mode presents the idea of a named passive interface, which enables administrators of networks to exercise control over the flow of routing information on particular interfaces. A passive interface is one that does not actively participate in EIGRP routing updates. This can be understood in the context of this discussion. In EIGRP Named Mode, administrators have the ability to easily apply the passive behavior to many interfaces that share the same features. This is accomplished by assigning a name to a passive interface. By providing a method that is both more structured and scalable for setting passive interfaces, this improves network management through its implementation. EIGRP Named Passive Interface, in its most basic form, streamlines the process of restricting routing updates on certain interfaces. This, in turn, contributes to the enhancement of network stability and security by eliminating the interchange of unnecessary information on designated links.
LAB:
Task 1: The first task is to configure the IPv4 EIGRP process with a passive interface by utilizing a dedicated configuration.
Step 1: The first step is to configure the EIGRP process with a name and a network address of 0.0.0.0 by executing the command in the configuration mode of the router.
R2:
router eigrp cisco
address-family ipv4 autonomous-system 100
network 0.0.0.0
exit
Step 2: Use the “passive-interface” command to turn off EIGRP updates and enter the address-family default interface configuration mode.
