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.

ip ospf 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.

address connected to the current interface. If not specified, the

command applies to all networks connected to the current interface.
