BSCI - Manipulating Routing Updates - Routing Table Codes

I got caught out during some practice questions on routing table codes. So I thought it might be an idea to list the out put from #sh ip route and just set down what they are.

Simple question to nail - given the codes [X, Y, Z] which is the least trust worthy. I should have had this down from my CCNA but there you are. You need to first understand what the code is, then cross reference it with a suitable Administrative Distance. (Check my Charts and Table page above if you're unsure of the AD for a given protocol)

Protocol code:

C - connected,
S - static,
R - RIP,
M - mobile
B - BGP
D - EIGRP,
EX - EIGRP external,
O - OSPF,
IA - OSPF inter area
N1 - OSPF NSSA external type 1,
N2 - OSPF NSSA external type 2
E1 - OSPF external type 1,
E2 - OSPF external type 2
i - IS-IS,
su - IS-IS summary,
L1 - IS-IS level-1,
L2 - IS-IS level-2
ia - IS-IS inter area,
* - candidate default,
U - per-user static route
o - ODR,
P - periodic downloaded static route
