•
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.
•
hello-interval <
seconds
>
- Specifies the transmit delay
between sending hello packets. Setting the hello interval to a
smaller value can reduce the delay in detecting topological
changes, but will increase the routing traffic. This value must be
the same for all routers attached to an autonomous system.
(Range: 1-65535 seconds; Default: 10 seconds)
•
retransmit-interval <
seconds
>
- Specifies the interval
at which the ABR retransmits link-state advertisements (LSA)
over the virtual link. The retransmit interval should be set to a
conservative value that provides an adequate flow of routing
information, but does not produce unnecessary protocol traffic.
However, note that this value should be larger for virtual links.
(Range: 1-3600 seconds; Default: 5 seconds)
•
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: 1-3600 seconds;
Default: 1 seconds)
•
dead-interval <
seconds
>
- Specifies the time that
neighbor routers will wait for a hello packet before they declare
the router down. This value must be the same for all routers
attached to an autonomous system. (Range: 1-
65535 seconds; Default: 4 x hello interval, or 40 seconds)
•
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
