Configuring OSPF

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 for OSPF point-to-point link

This feature is supported on 1 Gbps Ethernet and 10 Gbps Ethernet interfaces.

This feature is supported on physical interfaces. It is not supported on virtual interfaces.

Brocade supports numbered point-to-point networks, meaning the OSPF router must have an
IP interface address which uniquely identifies the router over the network. Brocade does not
support unnumbered point-to-point networks.

Configuration syntax for OSFP point-to-point link

To configure an OSPF point-to-point link, enter commands such as the following.

Brocade(config)#interface eth 1/1/5

Brocade(config-if-e10000-1/1/5)#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

“Displaying OSPF neighbor information”

on page 217 and

on page 219.

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 226.

Enabling and disabling OSPF graceful restart

OSPF graceful restart is enabled by default on a Layer 3 switch. To disable it, use the following
commands.

Brocade(config)# router ospf

Brocade(config-ospf-router)# no graceful-restart

To re-enable OSPF graceful restart after it has been disabled, enter the following commands.

Brocade(config)# router ospf

Brocade(config-ospf-router)# graceful-restart

Syntax: [no] graceful-restart
