AT-WR4500 Series - IEEE 802.11abgh Outdoor Wireless Routers 101
RouterOS v3 Configuration and User Guide
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
authentication (none | simple | md5; default: none) - specifies authentication method for OSPF
protocol messages
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
type (default | stub; default: default) - 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 AREA-ID STUB DEFAULT-COST AUTHENTICATION
0 backbone 0.0.0.0 none
1 local_10 0.0.10.5 no 1 none
[admin@WiFi] routing ospf area>
5.3.4 Networks
Submenu 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
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
Example
To enable the OSPF protocol on the 10.10.1.0/24 network, and include it into the backbone area, do the
following:
[admin@AT-WR4562] routing ospf network> add area=backbone network=10.10.1.0/24
[admin@AT-WR4562] routing ospf network> print
Flags: X - disabled
# NETWORK AREA
0 10.10.1.0/24 backbone
[admin@AT-WR4562] routing ospf>
