CASE STUDY:  ROUTING ISSUE 

1) server: ---> subnet

10.0.3.4/24 

10.8.3.97/24

--> dbserver1 10.8.3.97/24 --> 10.8.3.1

--> dbserver2 10.8.3.98/24 --> 10.8.3.1

--> dbserver3 10.8.3.99/24 --> 10.8.3.1

--> dbserver4 10.0.3.4/24 --> GW  10.8.3.1 ????


GATEWAY on linux:

ip r s

route -n

 --> routing ---> via (GATEWAY)

2) routing after reboot

ip r a

vi /etc/sysconfig/network-scripts/route-eth3


--> ISSUE about "changing gateway"

--> ping gateway


---> change the GATEWAY in /etc/sysconfig/network-scripts/route-eth3

---> restart network

systemctl restart network
