IP Routing Protocols AD

... I'm writing some tips after that for network administrators to be a quick reference instead of searching the Cisco or so on.By the way, you may know or remember IP routing protocols AD (Administrative Distance) but don't remember some of them or are unknown for you.Ask me the ones.Meanwhile I'll tell the quick command related to changing ADs.

Connected interface = 0
Static route = 1
Enhanced Interior Gateway Routing Protocol (EIGRP) summary route = 5
External Border Gateway Protocol (BGP) = 20
Internal EIGRP = 90
IGRP = 100
OSPF = 110
Intermediate System-to-Intermediate System (IS-IS) = 115
Routing Information Protocol (RIP) = 120
Exterior Gateway Protocol (EGP) = 140
On Demand Routing (ODR) = 160
External EIGRP = 170
Internal BGP = 200
Unknown = 255

Tip-1:
To change the AD :
-For EIGRP:
Router(config)#distance eigrp [internal-distance] [external-distance]
-For other protocols:
Router(config-router)#distance [weight] ...
