Parameters seconds — Enter the hello-interval value in seconds (1 to 65535).
Default 10 seconds
Command Mode INTERFACE
Usage Information All routers in a network must have the same hello time interval between the hello packets. The no version of the
this command resets the value to the default.
Example
OS10(conf-if-vl-10)# ip ospf hello-interval 30
Supported Releases 10.2.0E or later
ip ospf message-digest-key
Enables OSPF MD5 authentication and sends an OSPF message digest key on the interface.
Syntax
ip ospf message-digest-key keyid md5 key
Parameters
• keyid — Enter an MD5 key ID for the interface (1 to 255).
• key — Enter a character string as the password (up to 16 characters).
Defaults Not congured
Command Mode INTERFACE
Usage Information All neighboring routers in the same network must use the same key value to exchange OSPF information. The no
version of this command deletes the authentication key.
Example
OS10(config)# interface ethernet 1/1/1
OS10(conf-if-eth1/1/1)# ip ospf message-digest-key 2 md5 sample12345
Supported Releases 10.3.0E or later
ip ospf mtu-ignore
Enables OSPF MTU mismatch detection on receipt of DBD packets.
Syntax
ip ospf mtu-ignore
Parameters None
Default Not congured
Command Mode INTERFACE
Usage Information When neighbors exchange DBD packets, the OSPF process checks if the neighbors are using the same MTU on a
common interface. If the receiving MTU in the DBD packet is higher than the IP MTU congured on the incoming
interface, OSPF adjacency does not establish. The no version of this command disables the IP OSPF mtu-ignore
conguration.
Example
OS10(conf-if-vl-10)# ip ospf mtu-ignore
Supported Releases 10.2.0E or later
