I have 4507R multi-layer switch and EIGRP is configured for dynamic routing.
router eigrp 101
network 10.223.12.0 0.0.3.255
network 10.223.17.0 0.0.0.255
network 10.223.18.0 0.0.0.255
By default EIGRP's auto-summarization is ON, based on the configuration above, I want to disable auto-summarization as the network defined were not contigous network. Please advice if the steps I want to take is appropriate. I am also attaching the configuration of our 4507R core switch. Any advice that will help optimize our core switch is greatly appreciated. Thanks.
