– 1773 –
seconds - Interval at which hello packets are sent from an interface.
This interval must be set to the same value for all routers on the
network. (Range: 1-65535)

Hello packets are used to inform other routers that the sending router is
still active. Setting the hello interval to a smaller value can reduce the
delay in detecting topological changes, but will increase routing traffic.

message-digest-key
This command enables message-digest (MD5) authentication on the
specified interface and to assign a key-id and key to be used by
neighboring routers. Use the no form to remove an existing key.

ip ospf [ ip-address ] message-digest-key key-id md5 key
no ip ospf [ ip-address ] message-digest-key key-id
ip-address - This parameter can be used to indicate a specific IP
address connected to the current interface. If not specified, the
command applies to all networks connected to the current interface.
key-id - Index number of an MD5 key. (Range: 0-255)
key - Alphanumeric password used to generate a 128 bit message
digest or “fingerprint.” (Range: 1-16 characters)

◆ Before specifying MD5 authentication for an interface with the ip ospf
authentication command, configure the message-digest key-id and key
with this command.
◆ Normally, only one key is used per interface to generate authentication
information for outbound packets and to authenticate incoming
