Configuring OSPF with ABR on SteelHead SD
You can configure one or more summary addresses matching the individual addresses to advertise to a
OSPF peer. You can also advertise individual addresses. By default, only summary addresses are
advertised.
Figure 7-15. Summarizing routes for OSPF
5. Click Automatic to have SCM calculate the prefixes automatically, or click Manual to specify the
summarized prefix.
For automatic prefix calculation, specify a starting and an ending IP address. The system provides
the summarized prefix. For example, entering the starting address 160.0.1.0 and the ending address
160.0.2.0 results in the automatic prefix 160.0.0.0/22.
6. Fill out the these attributes for automatic or manual:
• Summarized Prefix - Specify the IP prefix designated for the range of addresses, including the prefix
length.
• Advertise - Click On to advertise the summary prefix. Click Off to stop advertisements of the
summary address.
• Tag - Specify a 32-bit value attached to the summary route. The specified value will be tagged to
the advertised summary routes.
7. Click Submit .
Viewing OSPF status
There are multiple places where SCM provides visibility to OSPF and the state of routes.
To view OSPF routing tables
1. Choose Health Check > Routing Tables.
2. Select the OSPF tab and select the appliance to display the OSPF neighbors and learned routes.
To view the Forward Information Base (FIB) routing table
1. Choose Health Check > Routing Tables.
2. Select the FIB tab and select the appliance to display the FIB information, including destination, next
hop, metric value, route type, and subroute type. This table is very useful and should be the first step
in debugging if the expected routes are learned by the appliance.
