Configure vIOS routers as following.
Router#conf t
Router(config)#hostname vOS-I
vIOS-I(config)#interface GigabitEthernet 0/0
vIOS-I(config-if)#ip address
vIOS-I(config-if)#no shutdown
vIOS-I(config-if)#do wr

List Routing Table
Router2#show ip route

Default GW
Router(config)#ip route

Enable SSh @ router

Router (config)# username admin privilege 15 secret Firewall.cx      (Firewall.cx <- nbsp="" password="" ssh="" strong="" to="">
Router (config)# aaa new-model
Router (config)# aaa authentication login default local
Router (config)# enable secret $FirewAll.cx!           <- en="" mode="" nbsp="" password="" strong="" to="">
Router (config)# service password-encryption

R1(config)# line vty 0 4
R1(config-line)# transport input ssh
R1(config-line)# login authentication default
R1(config-line)# password $Cisco!    <- aaa="" authentication="" cisco="" guna="" nbsp="" ni="" pakai="" password="" sebab="" strong="" tak="">

Generating RSA key  (selagi takde key, ssh port tak enable)
R1 (config)#  ip domain-name firewall.cx
R1(config)# crypto key generate rsa 
The name for the keys will be: R1.firewall.cx
Choose the size of the key modulus in the range of 360 to 4096 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes.                                                                                                                                                                                                     How many bits in the modulus [512]: 4096
% Generating 4096 bit RSA keys, keys will be non-exportable...
[OK] (elapsed time was 183 seconds)


Remove ospf process:
R1(conf)#  no router ospf 1
