Example
To enable the OSPF protocol redisrtibute routes to the connected networks as type1 metrics with
the cost of 1, you need do the following:
[admin@MikroTik] routing ospf> set redistribute-connected=as-type-1 \
\... metric-connected=1
[admin@MikroTik] routing ospf> print
router-id: 0.0.0.0
distribute-default: never
redistribute-connected: as-type-1
redistribute-static: no
redistribute-rip: no
redistribute-bgp: no
metric-default: 1
metric-connected: 1
metric-static: 20
metric-rip: 20
metric-bgp: 20

Areas
Home menu level: /routing ospf area
Description
OSPF allows collections of routers to be grouped together. Such group is called an area. Each area
runs a separate copy of the basic link-state routing algorithm. This means that each area has its own
link-state database and corresponding graph
The structure of an area is invisible from the outside of the area. This isolation of knowledge
enables the protocol to effect a marked reduction in routing traffic as compared to treating the entire
Autonomous System as a single link-state domain
60-80 routers have to be the maximum in one area
Property Description
area-id ( IP address ; default: 0.0.0.0 ) - OSPF area identifier. Default area-id=0.0.0.0 is the
backbone area. The OSPF backbone always contains all area border routers. The backbone is
responsible for distributing routing information between non-backbone areas. The backbone must
be contiguous. However, areas do not need to be physical connected to backbone. It can be done
with virtual link. The name and area-id for this area can not be changed
authetication ( none | simple | md5 ; default: none ) - specifies authentication method for OSPF
