Configuring OSPF

OSPF point-to-point links
In an OSPF point-to-point network, where a direct Layer 3 connection exists between a single pair of
OSPF routers, there is no need for Designated and Backup Designated Routers, as is the case in
OSPF multi-access networks. Without the need for Designated and Backup Designated routers, a
point-to-point network establishes adjacency and converges faster. The neighboring routers
become adjacent whenever they can communicate directly. In contrast, in broadcast and
non-broadcast multi-access (NBMA) networks, the Designated Router and Backup Designated
Router become adjacent to all other routers attached to the network.
NOTE
This feature is supported on Gigabit Ethernet and 10-Gigabit Ethernet interfaces.
NOTE
This feature is supported on physical interfaces. It is not supported on virtual interfaces.
NOTE
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.
Configuring an OSPF point-to-point link
To configure an OSPF point-to-point link, enter commands such as the following.
BigIron RX(config)# interface eth 1/5
BigIron RX(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
You can use the show ip ospf interface command to display OSPF point-to-point information. Enter
the following command at any CLI level.
Syntax: show ip ospf interface [<ip-addr>]
The <ip-addr> parameter displays the OSPF interface information for the specified IP address.
BigIron RX# show ip ospf interface 192.168.1.1
