Configuring OSPF
• ip ospf md5-authentication key-activation-wait-time num | key-id num key string
• ip ospf mtu-ignore
• ip ospf passive
• ip ospf active
• ip ospf priority value
• ip ospf retransmit-interval value
• ip ospf transmit-delay value
For a complete description of these parameters, see the summary of OSPF port parameters in the
next section.
OSPF interface parameters
The following parameters apply to OSPF interfaces:
TABLE 17 OSPF interface parameter output descriptions.
Table 0.1:
area Assigns an interface to a specific area. You can assign either an IP address
or number to represent an OSPF Area ID. If you assign a number, it can be
any value from 0 – 2,147,483,647.
auth-change-wait-time OSPF gracefully implements authentication changes to allow all routers to
implement the change and thus prevent disruption to neighbor
adjacencies. During the authentication-change interval, both the old and
new authentication information is supported. The default
authentication-change interval is 300 seconds (5 minutes). You change
the interval to a value from 0 – 14400 seconds.
authentication-key string By default, the authentication key is encrypted. If you want the
authentication key to be in clear text, insert a 0 between key and string.
For example,
Brocade(config-if-e10000-1/8)# ip ospf
authentication-key 0 morningadmin
The software adds a prefix to the authentication key string in the
configuration. For example, the following portion of the code has the
encrypted code “2”.
ip ospf authentication-key 2 $on-o
The prefix can be one of the following:
•
0 = the key string is not encrypted and is in clear text
•
1 = the key string uses proprietary simple cryptographic 2-way
algorithm
•
2 = the key string uses proprietary base64 cryptographic 2-way
algorithm (only for Brocade NetIron XMR and Brocade MLX series
devices)
cost Indicates the overhead required to send a packet across an interface. You
can modify the cost to differentiate between 100 Mbps, 1Gbps, and 10
Gbps. The default cost is calculated by dividing 100 million by the
bandwidth. For 10 Mbps links, the cost is 10. The cost for 100 Mbps,
1Gbps, and 10 Gbps links is 1, because the speed of 100 Mbps and
10Gbps was not in use at the time the OSPF cost formula was devised.
database-filter Blocks all outbound LSAs on the OSPF interface.
