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
