EIGRP
Router eigrp (AS Number)
Show commands show ip eigrp ?
Adding connected networks

Router config
Passive-interface (interface)
Bandwidth-percent, hello-interval, hold-time
Go into interface. Ip hold-time/hello-interval/bandwidth-percent eigrp (AS number) $
Auto Summary
Auto summary useful if using subnets across routers
In router config auto-summary/no auto-summary
Encryption
Go to conf t

Redistribution
Into EIGRP
Enter Router EIGRP
Redistribute protocol [process-id] [metric metric-value]
Metric value for redistributing into EIGRP is > bandwidth, delay, reliability, load, and maximum transmission unit (MTU).
Redistribute ospf <area> metric 100000 10 255 1 1500
Into OSPF
Enter router OSPF
Redistribute protocol [process-id] [metric metric-value] [metric-type type-value] [subnets]
Subnets specifies subnets to be redistributed into the routing protocol, if not specified only classful routes will be used
Metric type = 1 or 2, this is E1 vs E2.
Into RIP
Redistribute protocol [process-id] [match route-type] [metric metric-value] [route-map map-tag]
Match and map tag are optional.
Extended ping
Type ping
Yes when asking for extended commands
Change source.
DHCP
Ip dhcp <command>
use ? for further commands – very simple
show ip dhcp binding
