protocol message headers. A separate password can be
assigned to each network interface. However, this key must be
the same for all neighboring routers on the same network (that
is, autonomous system). This key is only used when
authentication is enabled for the backbone.
• message-digest-key <key-id> md5 <key> - Sets the
key identifier and password to be used to authenticate protocol
messages passed between neighboring routers and this router
when using message digest (MD5) authentication. The key-id is
an integer from 1-255, and the key is an alphanumeric string up
to 16 characters long. If MD5 authentication is used on a virtual
link, then it must be enabled on all routers within an
autonomous system; and the key identifier and key must also
be the same for all routers.

Command Usage
• All areas must be connected to a backbone area (0.0.0.0) to maintain
routing connectivity throughout the autonomous system. If it is not
possible to physically connect an area to the backbone, a virtual link can
be used. A virtual link can provide a logical path to the backbone for an
isolated area. Up to 32 virtual links can be specified on this router.
• Any area disconnected from the backbone must include the transit area
ID and the router ID for a virtual link neighbor that is adjacent to the
backbone.
