Hello i have 4 pc with 2 routers PC1 PC2 in Router1 and PC5 PC6 in Router2. I can ping PC1 to PC2 and Router1 same for PC5 PC6 Router2 but i cant ping PC1 to PC5 PC6 Router2 and other way around.

When i try to ping PC5 PC6 and Router2 it says  *Reply from 192.168.20.1: Destination host unreachable.*

Hello,

you need to decide which routing protocol to use, and announce the correct networks. I have configured OSPF like below (working file attached):

R1

router ospf 1
log-adjacency-changes
network 172.16.30.0 0.0.0.3 area 0
network 192.168.10.0 0.0.0.255 area 0

R2

router ospf 1
log-adjacency-changes
network 172.16.30.0 0.0.0.3 area 0
network 192.168.20.0 0.0.0.255 area 0
