Adding additional parameters
The memory option logs abnormal OSPF memory usage. This option is enabled by default.
The retransmit option logs OSPF retransmission activities. This option is disabled by default.
Configuring an OSPF network type
To configure an OSPF network, enter commands such as the following.
Brocade(config)# interface eth 1/5
Brocade(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 | broadcast | non-broadcast
The point-to-point option configures the network type as a point to point connection.
NOTE
Brocade devices support numbered point-to-point networks, meaning the OSPF router must have an
IP interface address which uniquely identifies the router over the network. Brocade devices do not
support unnumbered point-to-point networks.
The broadcast option configures the network type as a broadcast connection. This is the default
option for Ethernet, VE and Loopback interfaces.
The non-broadcast option configures the network type as a non-broadcast connection. This allows
you to configure the interface to send OSPF traffic to its neighbor as unicast packets rather than
multicast packets. This can be useful in situations where multicast traffic is not feasible (for
example when a firewall does not allow multicast packets).
On a non-broadcast interface, the routers at either end of this interface must configure
non-broadcast interface type and the neighbor IP address. There is no restriction on the number of
routers sharing a non-broadcast interface (for example, through a hub/switch).
To configure an OSPF interface as a non-broadcast interface, you enable the feature on a physical
interface or a VE, following the ip ospf area statement, and then specify the IP address of the
neighbor in the OSPF configuration. The non-broadcast interface configuration must be done on
the OSPF routers at either end of the link.
For example, the following commands configure VE 20 as a non-broadcast interface.
Brocade(config)# int ve 20
Brocade(config-vif-20)# ip address 10.1.20.4/24
Brocade(config-vif-20)# ip ospf area 0
Brocade(config-vif-20)# ip ospf network non-broadcast
The following commands specify 10.1.20.1 as an OSPF neighbor address. The address specified
must be in the same sub-net as the non-broadcast interface.
Brocade(config)# router ospf
Brocade(config-ospf-router)# neighbor 10.1.20.1
For example, to configure the feature in a network with three routers connected by a hub or switch,
each router must have the linking interface configured as a non-broadcast interface, and the two
other routers must be specified as neighbors.
Configuring OSPF Graceful Restart
OSPF Graceful Restart can be enabled in the following configurations:
