using IP default route to ping between multiple routers

using IP default route to ping between multiple routers


I have the topology above

I can ping from all routers to router RITE interfaces. However I cannot ping from router Client to router Internet or IDS , nor from IDS to Client and Internet, nor from Internet to Client or IDS.

for now I am interested to ping from Client to Internet. I have configured default route on Client router , but there is no luck.

Internet#sh ip interface brief | inc up
Ethernet0/0                192.168.14.2    YES NVRAM  up                    up      


RITE#sh ip interface brief | inc up
Ethernet0/0                192.168.14.1    YES NVRAM  up                    up      
Ethernet0/1                192.168.13.1    YES NVRAM  up                    up      
Ethernet1/0                192.168.12.1    YES NVRAM  up                    up      
RITE#


Client#show ip interface brief | inc up
Ethernet0/0                192.168.12.2    YES NVRAM  up                    up      
Client#


Client(config)#ip route 0.0.0.0 0.0.0.0 192.168.12.1


Client#ping 192.168.14.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.14.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
Client#ping 192.168.14.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.14.2, timeout is 2 seconds:

we can see above Client router can ping the interface 192.168.14.2 (interface connecting RITE router to IINTERNET router), but cannot ping INTERNET router interface 192.168.14.2

any help ?

Thank you
