ip ospf
Use the ip ospf command to customize OSPF settings (if needed).
Syntax Description
authentication-key Specifies a simple-text authentication password to be used
by other routers using <password> the OSPF simple
password authentication.
cost <value> Specifies the OSPF cost of sending a packet on the interface.
This value overrides any computed cost value.
Range: 1 to 65535.
dead-interval <seconds> Sets the maximum interval allowed between hello packets. If
the maximum is exceeded, neighboring devices will
determine that the device is down. Range: 0 to 32767.
hello-interval <seconds> Specifies the interval between hello packets sent on the
interface. Range: 0 to 32767.
message-digest-key <keyid> md5 <key>
Configures OSPF Message Digest 5 (MD5) authentication
(16-byte max) keys.
priority <value> Set the OSPF priority. The value set in this field helps
determine the designated router for this network.
Range: 0 to 255.
retransmit-interval <seconds> Specifies the time between link-state advertisements (LSAs).
Range: 0 to 32767.
transmit-delay <seconds> Sets the estimated time required to send an LSA on the
interface. Range: 0 to 32767.
Default Values
retransmit-interval <seconds> 5 seconds
transmit-delay <seconds> 1 second
hello-interval <seconds> 10 seconds: Ethernet, point-to-point, Frame Relay, and PPP
dead-interval <seconds> 40 seconds
Command Modes
(config-interface)# Interface Configuration Mode
Valid interfaces include: Ethernet (eth 0/1), virtual PPP interfaces (ppp 1), virtual
HDLC interfaces (hdlc 1), virtual Frame Relay sub-interfaces (fr 1.20), tunnel
interfaces (tunnel 1), and VLAN interface (vlan 1).
Usage Example
The following example sets the maximum number of seconds allowed between hello packets to 25,000:
(config)#interface hdlc 1
(config-hdlc 1)#ip ospf dead-interval 25000
