Configuring OSPF
6
Hello-interval: Represents the length of time between the transmission of hello packets. The value
can be
from 1 – 65535 seconds. The default is 10 seconds.
MD5-authentication activation wait time: The number of seconds the Layer 3 Switch waits until
placing a new MD5 key into effect. The wait time provides a way to gracefully transition from one
MD5 key to another without disturbing the network. The wait time can be from 0 – 14400 seconds.
The default is 300 seconds (5 minutes).
MD5-authentication key ID and key: A method of authentication that requires you to configure a
key ID and an MD5 key. The key ID is a number from 1 – 255 and identifies the MD5 key that is
being used. The MD5 key consists of up to 16 alphanumeric characters. The MD5 is encrypted and
included in each OSPF packet transmitted.
Passive: When you configure an OSPF interface to be passive, that interface does not send or
receive OSPF route updates. By default, all OSPF interfaces are active and thus can send and
receive OSPF route information. Since a passive interface does not send or receive route
information, the interface is in effect a stub network. OSPF interfaces are active by default.
NOTE
This option affects all IP subnets configured on the interface. If you want to disable OSPF updates
only on some of the IP subnets on the interface, use the ospf-ignore or ospf-passive parameter with
the ip address command. Refer to
“Assigning an IP address to an Ethernet port” on page 55.
Priority: Allows you to modify the priority of an OSPF router. The priority is used when selecting the
designated router (DR) and backup designated routers (BDRs). The value can be from 0 – 255. The
default is 1. If you set the priority to 0, the Layer 3 Switch does not participate in DR and BDR
election.
Retransmit-interval: The time between retransmissions of link-state advertisements (LSAs) to
adjacent routers for this interface. The value can be from 0 – 3600 seconds. The default is 5
seconds.
Transit-delay: The time it takes to transmit Link State Update packets on this interface. The value
can be from 0 – 3600 seconds. The default is 1 second.
Encrypted display of the authentication string or MD5 authentication key
The optional 0 | 1 parameter with the authentication-key and md5-authentication key-id
parameters affects encryption.
For added security display of the password or authentication string is encrypted. Encryption is
enabled by default. The software also provides an optional parameter to disable encryption of a
password or authentication string, on an individual OSPF area or OSPF interface basis.
When encryption of the passwords or authentication strings is enabled, they are encrypted in the
CLI regardless of the access level you are using. In the Web management interface, the passwords
or authentication strings are encrypted at the read-only access level but are visible at the
read-write access level.
The encryption option can be omitted (the default) or can be one of the following:
• 0 – Disables encryption for the password or authentication string you specify with the
command. The password or string is shown as clear text in the running-config and the
startup-config file. Use this option of you do not want display of the password or string to be
encrypted.
