– 855 –
transmit-delay
seconds
- Estimates the time required to send a link-state
update packet over the virtual link, considering the transmission and
propagation delays. LSAs have their age incremented by this amount
before transmission. This value must be the same for all routers attached to
an autonomous system. (Range: 1-65535 seconds; Default: 1 second)
authentication
- Specifies the authentication mode. If no optional
parameters follow this keyword, then plain text authentication is used
along with the password specified by the
authentication-key
. If
message-
digest
authentication is specified, then the
message-digest-key
and
md5
parameters must also be specified. If the
null
option is specified, then no
authentication is performed on any OSPF routing protocol messages.
message-digest
- Specifies message-digest (MD5) authentication.
null
- Indicates that no authentication is used.
authentication-key
key
- Sets a plain text password (up to 8 characters)
that is used by neighboring routers on a virtual link to generate or verify
the authentication field in 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 (i.e., 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 0-255, 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 not possible to physically
connect an area to the backbone, you can use a virtual link. A virtual link can
provide a logical path to the backbone for an isolated area, or can be
