IP Routing Table!

Hi people,

Can someone explain to me, how can one interpret or distinguish the routes from the routing table? (eigrp,ospf)

Re: IP Routing Table!

Hi,

The show ip route will show how the particular route installed to the route table.

Codes:

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

If the router has learned the same prefix through other protocols the administrative distance will judge. The lower one will take precedence over the lower.

AD's:

Connected 0

Static 1

EIGRP summary 5

EBGP 20

Internal EIGRP 90

IGRP 100

OSPF 110

IS-IS 115

RIP 120

EGP 140

ODR 160

External EIGRP 170

iBGP 200

Unknown 255

Hope it helps,

Krisztian

Re: IP Routing Table!

Correction:

The lower one will take precedence over the higher. (connected is the strongest)
