Configuring OSPF
29
NOTE
PowerConnect devices dynamically allocate OSPF memory as needed. Refer to “Dynamic OSPF
memory” on page 930.
To modify the exit overflow interval to 60 seconds, enter the following command.
PowerConnect(config-ospf-router)#database-overflow-interval 60
Syntax: database-overflow-interval <value>
The <value> can be from 0 through 86400 seconds. The default is 0 seconds.
Configuring an OSPF point-to-point link
In an OSPF point-to-point link, a direct Layer 3 connection exists between a single pair of OSPF
routers, without the need for Designated and Backup Designated routers. In a point-to-point link,
neighboring routers become adjacent whenever they can communicate directly. In contrast, in
broadcast and non-broadcast multi-access (NBMA) networks, the Designated Router and the
Backup Designated Router become adjacent to all other routers attached to the network.
Configuration notes and limitations
• This feature is supported on Gbps Ethernet and 10 Gbps Ethernet interfaces.
• This feature is supported on physical interfaces. It is not supported on virtual interfaces.
• Dell supports numbered point-to-point networks, meaning the OSPF router must have an IP
interface address which uniquely identifies the router over the network. Dell does not support
unnumbered point-to-point networks.
Configuration syntax
To configure an OSPF point-to-point link, enter commands such as the following.
PowerConnect(config)#interface eth 1/5
PowerConnect(config-if-1/5)#ip ospf network point-to-point
This command configures an OSPF point-to-point link on Interface 5 in slot 1.
Syntax: [no] ip ospf network point-to-point
Viewing configured OSPF point-to-point links
Refer to “Displaying OSPF neighbor information” on page 969 and “Displaying OSPF interface
information” on page 971.
Configuring OSPF graceful restart
By default, OSPF graceful restart is enabled for the global instance.
For information about how to display OSPF graceful restart information, refer to “Displaying OSPF
graceful restart information” on page 978.
