Hello Iynkaran
The EIGRP course contains every lesson on the site that has to do with EIGRP. It includes the most basic explanations found in CCNA all the way through to CCNP and CCIE. So you don’t have to go through the individual EIGRP sections in the CCNA, ENCOR, ENARSI, and CCIE Enterprise courses. If you want to go through everything EIGRP, from the very beginning the EIGRP course covers it all.
I hope this has been helpful!
