Cant able to see directly connected netoworks # RIP

I am not able to see directly connected networks even when I have a connected multiple networks.
========= sh run========

interface Loopback0

ip address 192.168.1.1 255.255.255.0

!

interface FastEthernet0/0

ip address 15.1.1.1 255.0.0.0

duplex auto

speed auto

shutdown

!

interface FastEthernet0/1

ip address 13.1.1.1 255.0.0.0

duplex auto

speed auto

shutdown

!

interface FastEthernet1/0

ip address 12.1.1.1 255.0.0.0

duplex auto

speed auto

shutdown

=========sh IP route========
Delhi#sh ip route
Codes: L - local, 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, E - EGP
i - IS-IS, 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

Gateway of last resort is not set

 192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks

C 192.168.1.0/24 is directly connected, Loopback0
L 192.168.1.1/32 is directly connected, Loopback0

Ques: Why there is no directly connected network is showing?

As I can see only the network advertised on the loopback interface is being added to the routing table, it is happening because the loopback interface is in UP state. But the physical ports/interfaces like fastethernet 0/0, fastethernet0/1 and fastethernet1/0 of the router are not moved to UP state. You need to run the “no shutdown” command under the physical interfaces for them to move in UP and running state.

R(config)#interface fastethernet 0/0
# ip address15.1.1.1 255.0.0.0
# no shutdown

** the loopback interface is a logical interface and thus it moves to UP state automatically as it is created. But for the physicak interfaces of the Router we need to manually bring it UP.

Hope this helps!
Thanks!
