OSPF routing between Cisco Router and Mikrotik Router

For this I have used GNS3 for cisco router and Virtual box for mikrotic router. Cisco router in GNS3 is connected to a host which is configured by my LAN card adapter. Mikrotic router  is connected to also LAN  by bridging in virtualbox.
GNS3 Settings

Virtual box setting
C

Cisco Router IP                                           Mikrotic Router IP
      G0/0: 192.168.0.60/24                                 ether1: 192.168.0.50/24
      loopback1: 2.2.2.2/24                                    loopback1:1.1.1.1/24
      ospf area 400                                                 ospf area id: 0.0.1.144
                                                                           
Area ID calculation in Mikrotic, convert 400 decimal into binary (i.e. 110010000). The binary number needs to show 32 digits, representing the digits of the 4 octets in the IP type format. So, 110010000 binary = 00000000.00000000.0000001.10010000 as broken into octets. Finally, convert each octet into a decimal value. (e.g. 00000000.00000000.0000001.10010000 = 0.0.1.144). Therefore, 400 = 0.0.1.144
Command in Cisco 
R1>ena
R1#conf t
R1(config)#int loopback 1
R1(config-if)#ip address 2.2.2.0 255.255.255.0
R1(config-if)#no shut
R1(config)#int G0/0 
R1(config-if)#ip address 192.168.1.0 255.255.255.0
R1(config-if)#no shut

R1(config)#router ospf 1
R1(config-router)#network 192.168.0.0 0.0.0.255 area 400
R1(config-router)#network 2.2.2.0 0.0.0.255 area 400
R1(config-router)#

Command in Mikrotic


[jahid@MikroTik] >
[jahid@MikroTik] > interface bridge add name=loopback1
[jahid@MikroTik] > ip address add address=1.1.1.1/24 interface=loopback1
[jahid@MikroTik] > ip address add address=192.168.0.50/30 interface=ether1
[jahid@MikroTik] >
[jahid@MikroTik] > routing ospf
[jahid@MikroTik] /routing ospf> area add name=area400 area-id=0.0.1.144
[jahid@MikroTik] /routing ospf> network add network=192.168.0.0/24 area=

Area ::= area1 | area2 | area5 | area400 | limon | ...

[jahid@MikroTik] /routing ospf> network add network=192.168.0.0/24 area=area400
[jahid@MikroTik] >
[jahid@MikroTik] >

Then Checking in cisco



Then Checking in Mikrotik






Thank you everybody.
