Use the show config command in CONFIGURATION INTERFACE mode to view interface
configurations. Use the
show ip ospf interface command in EXEC mode to view interface status in the
OSPF process.

ip ospf
message-digest-key
keyid md5 key
CONFIG-INTERFACE Use the MD5 algorithm to produce a message digest or key,
which is sent instead of the key.
Keyid range: 1 to 255
Key: a character string
Be sure to write down or otherwise record the Key. You cannot learn the key once it is
configured.
You must be careful when changing this key.
ip ospf priority
number
CONFIG-INTERFACE Change the priority of the interface, which is used to determine
the Designated Router for the OSPF broadcast network.
Number range: 0 to 255 (the default is 1).
ip ospf
retransmit-interval
seconds
CONFIG-INTERFACE Change the retransmission interval between LSAs.
Seconds range: from 1 to 65535 (default is 5 seconds).
The retransmit interval must be the same on all routers in the OSPF network.
ip ospf
transmit-delay
seconds
CONFIG-INTERFACE Change the wait period between link state update packets sent out
the interface. Seconds range: from 1 to 65535 (default is 1
second).
The transmit delay must be the same on all routers in the OSPF network.
