Networks - MikroTik RouterOS v2.9 Reference Manual

• none - do not use authentication
• simple - plain text authentication
• md5 - keyed Message Digest 5 authentication
default-cost ( integer ; default: 1 ) - specifies the default cost used for stub areas. Applicable only
to area boundary routers
name ( name ; default: "" ) - OSPF area's name
stub ( yes | no ; default: no ) - a stub area is an area which is out from part with no routers or areas
beyond it. A stub area is configured to avoid AS External Link Advertisements being flooded into
the Stub area. One of the reason to configure a Stub area is that the size of the link state database is
reduced along with the routing table and less CPU cycles are used to process. Any router which is
trying access to a network outside the area sends the packets to the default route
Example
To define additional OSPF area named local_10 with area-id=0.0.10.5, do the following:
[admin@WiFi] routing ospf area> add area-id=0.0.10.5 name=local_10
[admin@WiFi] routing ospf area> print
Flags: X - disabled, I - invalid
# NAME
0 backbone
1 local_10
[admin@WiFi] routing ospf area>

Networks

Home menu level: /routing ospf network
Description
There can be Point-to-Point networks or Multi-Access networks. Multi-Access network can be a
broadcast network (a single message can be sent to all routers)
To start the OSPF protocol, you have to define the networks on which it will run and the area ID for
each of those networks
Property Description
area ( name ; default: backbone ) - the OSPF area to be associated with the specified address range
network ( IP address/mask ; default: 20 ) - the network associated with the area. The network
argument allows defining one or multiple interfaces to be associated with a specific OSPF area.
Only directly connected networks of the router may be specified
Notes
You should set the network address exactly the same as the remote point IP address for
point-to-point links. The right netmask in this case is /32.
