ip ospf hello-interval Sets the time interval between the hello packets sent on the interface. Syntax ip ospf hello-interval seconds Parameters seconds - Enter the hello-interval value in seconds, from 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. NOTE: When you configure hello-interval for OSPF, the OSPF dead-interval value is implicitly set to a value four times greater than the hello-interval value. 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 Parameters ip ospf message-digest-key keyid md5 key • keyid - Enter an MD5 key ID for the interface, from 1 to 255. • key - Enter a character string as the password. A maximum of 16 characters. Defaults Not configured 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 configured 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 configured on the incoming interface, OSPF adjacency does not establish. The no version of this command disables the IP OSPF mtu-ignore configuration. Example OS10(conf-if-vl-10)# ip ospf mtu-ignore Supported Releases 10.2.0E or later 626 Layer 3
