Configuring OSPF
25
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 in Ironware software for BigIron RX releases 02.2.01 and later.
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>
]
BigIron RX# show ip ospf interface 192.168.1.1
