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.
The Dynamic Routing Network-Layer Protocol known as EIGRP operates on protocol number 88. It is a dynamic routing protocol. Classless routing, virtual local area network (VLSM), route summarization, load balancing, and a few other helpful features are all supported by EIGRP. It is a Cisco proprietary protocol, which means that all routers in a network that is running EIGRP must be Cisco routers. However, EIGRP is currently in the process of transitioning into an open standard protocol.
In order to facilitate communication amongst the routers that are running EIGRP, EIGRP exchanges messages.
Configuration:-
There is a small topology with three routers: Dallas, Houston & Autsin. This is where the user will set up EIGRP. As you can see, the Houston router needs to push the networks 10.10.10.0/24, 10.10.11.0/24, 172.16.10.0/30, and 172.16.10.4/30.
Because of this, we are now configuring EIGRP for the GfGBangalore router.
HOUSTON(config)#router eigrp 1
HOUSTON(config-router)#network 10.10.10.0
HOUSTON(config-router)#network 10.10.11.0
HOUSTON(config-router)#network 172.16.10.0
HOUSTON(config-router)#network 172.16.10.4
To begin, an EIGRP instance was initially formed by using the router eigrp 1 command, where 1 represents the number of the autonomous system. Now, in order to configure EIGRP for the AUSTIN router, the networks that need to be advertised are 10.10.40.0/24, 10.10.50.0/24, and 172.16.10.4/30.
AUSTIN(config)#router eigrp 1
AUSTIN(config-router)#network 172.16.10.4
AUSTIN(config-router)#network 10.10.50.0
AUSTIN config-router)#network 10.10.40.0
Now, set up EIGRP in the same way for DALLAS. The networks that will be advertised are 10.10.20.0/24, 10.10.30.0/24, and 172.16.10.0/30.
DALLAS(config)#router eigrp 1
DALLAS(config-router)#network 172.16.10.0
DALLAS(config-router)#network 10.10.20.0
DALLAS(config-router)#network 10.10.30.0
This is a straightforward setting where the user enters the network ID to be advertised using the network command.
