now from here on we can have some interesting part ...

let us see the routing tables of all the three routers

CODE

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

Gateway of last resort is not set

172.16.0.0/24 is subnetted, 2 subnets
C 172.16.0.0 is directly connected, Serial2/1
B 172.16.1.0 [20/0] via 172.16.0.1, 00:11:43
10.0.0.0/30 is subnetted, 1 subnets
C 10.0.0.0 is directly connected, Serial2/0
C 192.168.0.0/24 is directly connected, Loopback0
12.0.0.0/24 is subnetted, 1 subnets
