Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 290)

The log command has the following options:
The all option causes all OSPF-related Syslog messages to be logged. If you later disable this option
with the no log all command, the OSPF logging options return to their default settings.
The adjacency option logs essential OSPF neighbor state changes, especially on error cases. This
option is disabled by default. The dr-only sub-option only logs essential OSPF neighbor state changes
where the interface state is designated router (DR).
NOTE
For interfaces where the designated router state is not applicable, such as point-to-point and virtual
links, OSPF neighbor state changes will always be logged irrespective of the setting of the dr-only
sub-option.
NOTE
A limitation with the dr-only sub-option is that when a DR/BDR election is underway, OSPF neighbor
state changes pertaining to non-DR/BDR routers are not logged. Logging resumes once a DR is
elected on that network.
The bad_packet checksum option logs all OSPF packets that have checksum errors. This option is
enabled by default.
The bad_packet option logs all other bad OSPF packets. This option is disabled by default.
The database option logs OSPF LSA-related information. This option is disabled by default.
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.
device(config)# interface eth 1/5
device(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. This is the
default option for tunnel interfaces.
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).
