If you want to make the config smaller you could go with: cat1: router eigrp 100 no auto-summary network 0.0.0.0
cat2: router eigrp 100 no auto-summary network 0.0.0.0 cat4: router eigrp 100 no auto-summary network 0.0.0.0 But best practice is to use passive-interface default, and then only enable needed interfaces. /Ralph _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com
