Set OSPF authentication key to a cryptographic password. The cryptographic
algorithm is MD5. KEYID identifies secret key used to create the message
digest. KEY is the actual message digest key up to 16 chars. Note that OSPF
MD5 authentication requires that time never go backwards, even across
resets, if ospfd is to be able to promptly reestabish adjacencies with it's
neighbours after restarts/reboots. The host should have system time be set
at boot from an external source (eg battery backed clock, NTP, etc.) if MD5
authentication is to be expected to work reliably.

Note that OSPF MD5 authentication requires that time never go backwards

across resets, if ospfd is to be able to promptly reestabish adjacencies
with its neighbours after restarts/reboots. The host should have system
time be set at boot from an external source (eg battery backed clock, NTP,
etc.) or else the system clock should be periodically saved to non-volative
storage and restored at boot if MD5 authentication is to be expected to work
reliably.
