For the example topology above:
R0
----
Area: Backbone, id: 0.0.0.0
Area: R0_lan_area, id: 0.0.0.1
Area: R0_wlan_area, id: 0.0.0.2
Network 10.1.1.0/30 --> Backbone
Network 10.1.1.4/30 --> Backbone
Network 10.1.1.8/30 --> Backbone
Network 10.1.1.12/30 --> Backbone
Network 10.1.10.0/24 --> R0_lan_area
Network 10.1.11.0/24 --> R0_wlan_area
R1
----
Area: Backbone, id: 0.0.0.0
Area: R1_lan_area, id: 0.0.0.1
Network 10.1.1.0/30 --> Backbone
Network 10.1.11.0/24 --> R1_lan_area
R2
----
Area: Backbone, id: 0.0.0.0
Area: R2_lan_area, id: 0.0.0.1
Network 10.1.1.4/30 --> Backbone
Network 10.1.12.0/24 --> R2_lan_area
R3
----
Area: Backbone, id: 0.0.0.0
Area: R3_lan_area, id: 0.0.0.1
Network 10.1.1.8/30 --> Backbone
Network 10.1.13.0/24 --> R3_lan_area
R4
----
Area: Backbone, id: 0.0.0.0
Area: R4_lan_area, id: 0.0.0.1
Network 10.1.1.12/30 --> Backbone
Network 10.1.14.0/24 --> R4_lan_area
On top of that:
R0 has a static route 0.0.0.0/0 with gateway 10.1.1.18 for the IPs that need internet that have the right routing mark and with masquerading
All routers have 0.0.0.0/0 with gateway the relevant IP of R0 for each router
Is this correct? The Internet access is OK but I still don't see all IPs under each router while I can ping them from the router itself...
I find a little confusing the example in the manual here https://wiki.mikrotik.com/wiki/Manual:OSPF-examples when they write:
Code: Select all
/routing ospf network> add network=10.0.1.0/24 area=backbone
/routing ospf network> add network=10.1.2.0/30 area=area2
Or further up:
Code: Select all
[admin@MikroTikR1] /routing ospf network> add network=210.13.1.0/28 area=backbone
[admin@MikroTikR1] /routing ospf network> add network=10.10.1.0/30 area=backbone
[admin@MikroTikR1] /routing ospf network> add network=10.10.1.4/30 area=backbone
Area Questions:
- Is an Area a separate entity for each router or is it something shared across routers in an OSPF Network?
- What about their IDs? Are they supposed to be unique for the whole network or for each router?
- For example: R0_lan_area --> id: 0.0.0.1, R1_lan_area --> id: 0.0.0.1 Is this OK or should they have different IDs?
- Does having the same id for different areas mean that they are going to be shared by OSPF meaning that users can see each other between those areas?
In my example above I have a central Router through which everything connects. What if I ALSO wanted to connect for example R1 <--> R3 on top of that? What would change in the OSPF configuration?
Thanks in advance for your valuable input!
