Implementing EIGRP

Implementation
Configuration Basics
#Router eigrp 1
##network 192.168.1.0 0.0.0.255 [Wildcard optional]
#no auto-summary ! makes EIGRP classless
-Sends HELLO to form relationships
-advertise 192.168.1.0

Creating default route (gateway of last resort):
#ip route 0.0.0.0 0.0.0.0 s0/1
#Router EIGRP 1
# network 0.0.0.0

Verification
Useful Commands

sh ip Route
sh ip protocols !Verify what protocols are running
sh ip eigrp topology
sh ip eigrp neighbour ! Very good for troubleshooting
sh ip eigrp traffic
clear ip eigrp neighbours

EIGRP Summary
