Sanal,

Thanks in Advance.

Hello

Can you ping from RTR 1 to RTR2 sourced from its lan interface and the same fro RTR2

example -

R1 - 
ping 10.0.0.1 source fa0/0
ping 192.168.2.x source fa0/0

R2
ping 10.0.0.2 source fa0/0
ping 192.168.1.x source fa0/0

if you so check your pcs - for software fw negating echo-reply and their ip addressing/subnet/default-gateway

Hi Paul, thanks for helping me out.

yes i can ping all interfaces but not from pc to , from pc i can ping to its own interface and default gateway

Hi

Please correct me but you are using serial link between the routers, right?

What is the subnet mask of the network used on serial link?  10.0.0.0/8?

Your config should be using /30 

Router 1

interface serial 0/0

ip address 10.0.0.1 255.255.255.252 

clock rate 64000

no shutdown 

interface fa0/0

ip address 192.168.1.1 255.255.255.0

no shutdown 

ip route 192.168.2.0 255.255.255.0 10.0.0.2

Router 2

interface serial 0/0

ip address 10.0.0.2 255.255.255.252 

no shutdown 

interface fa0/0

ip address 192.168.2.1 255.255.255.0

no shutdown 

ip route 192.168.1.0 255.255.255.0 10.0.0.1

Your subnet masks on the 2 serial interfaces do not match.

[sanal9090]

i'm sorry i miss typed that subnetmask 

[sanal9090]

and im using T1 crossover cable t connect 

[Julio E. Moisa]

Hi

Have you tried matching the subnet mask on the P2P?

ip address 10.0.0.1 255.255.255.0

[mmanthe]

Are the servers and router ethernet ports connected to switches? If so, are all switchports set up in their respective vlans? Can each PC ping its respective (local) gateway (presumably the router’s ethernet port)?

[sanal9090]

Hi,
# yes, the routers connected to switches and there is no vlan configured (default vlan 1)

# yes, the pcs ping only to its local gateway

Switch#sh int fa0/1 switchport

Switchport: Enabled
Administrative Mode: static access
Operational Mode: static access
Administrative Trunking Encapsulation: dot1q
Operational Trunking Encapsulation: native

Access Mode VLAN: 1 (default)

Administrative Native VLAN tagging: enabled
Voice VLAN: none

Switch#sh int fa0/2 switchport

Switchport: Enabled

[paul driver]

Hello

So did you clarify the clients have the correct subnet mask and default-gateway.

When you ping between each client can you post the arp please

both rtrs:
sh ip arp

Lastly if applicable can you change the encapsulation from PPP to HDLC on the serial interfaces and test again

Still can't ping from 192.168.1.1 to 192.168.2.1

[mmanthe]

If you do a trace route from the pc to the other pc, where does it die? You could also ping each hop along the path to see where you start to lose connectivity (e.g. near-side ingress interface/default gateway, near-side serial interface, remote side serial interface, remote side exit/egress interface, etc.).
