network type cost

ethernet 10

T1 64

64kb/s 1562

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

[admin@MikroTik] routing ospf>

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

protocol messages
