Configuring OSPF with ABR on SteelHead SD
• Inherit OSPF Network Values - Click On to allow the OSPF network to inherit the OSPF network
values previously configured, such as password, hello interval, dead interval, priority, and cost.
Click Off to define unique settings for the network and to lock the network configuration so any
changes do not overwrite the settings. This OSPF network’s settings will change to match the new
values.
• OSPF Zone - Select the zone from the list. These are the zones that are participating in OSPF for the
area that is configured on this page. Only one zone interface per area is allowed.
• OSPF Uplinks - Select the uplinks from the list. These are the uplinks that will be participating in
OSPF in the area that is configure on this page.
• Inbound prefix - Optionally, specify the inbound prefix. Any prefixes defined in this prefix list are
used to filter networks sent to this area.
• Outbound prefix - Optionally, specify the outbound prefix. Any prefixes defined in this prefix list are
used to filter networks advertised from this area.
• Area ranges advertised - Specify a set of advertised routes to be advertised. In order to aggregate
routing information at area boundaries, area address ranges can be employed. Each address range
is specified by an [address, mask] pair.
• Area ranges not advertised - Specify the set routes that will not be advertised. In order to aggregate
routing information at area boundaries, area address ranges can be employed. Each address range
is specified by an [address, mask] pair. In this case, Type 3 summary-LSA is suppressed and the
component networks remain hidden from other areas.

Configuring redistribution settings for OSPF
The LAN/WAN routing interworking solution bridges eBGP and OSPF to redistribute underlay routing
information between the protocols on a gateway.
In 2.12, you can differentiate between static and overlay routes. Previously there was no differentiation
between overlay and static routes. To avoid this ambiguity, you can configure the Overlay to OSPF
option to distinguish overlay routes from static routes. The policies applied on redistribution of other
routes are also applicable on overlay routes
For details on how redistribution works, see the SteelConnect Manager User Guide .
To redistribute OSPF settings
1. Choose Routing and select the OSPF network.
