Does same subnet can ping eachother 192.168.0.0/30. can ping 192.168.0.13 this 192.168.0.2?

Hi Noor Sadat,

I actually got confused with your question,

See if the same subnet's  IPv4  address are configured  on the interfaces of two adjacent routers and they are directly connected to each other, then they will communicate with each other and would be able to ping each other too.

However the IPV4 address you have specified 192.168.0.0/30 wherein you specified prefix /30, which means subnet mask is 255.255.255.252 which gives 2 valid host IPs so pinging 192.168.0.2 with source ip 192.168.0.13 doesn't make any sense here.

I hope the above information has cleared your doubt.

CHEERS THANKS !! :)
