Parameter
route-id
: Router ID of virtual link peer.
dead seconds
: Specifies the interval of dead timer. It ranges from 1 to 8192 seconds.
This value must equal the
dead
seconds
of the router virtually linked to it and must be
at least four times of
hello
seconds
. The default value is 40 seconds.
dead minimal multi-hello packets
: Specifies the virtual link to run Fast Hello function.
The default dead is 1 second. The
packets
argument refers to the number of Hello
packets sent within 1 second, in the range of 3 to 10.
retransmit seconds:
Specifies the interval for re-transmitting the LSA packets on an
interface. It ranges from 1 to 8192 seconds. The default value is 5 seconds.
trans-delay
seconds:
Specifies the interval for delaying transmitting LSA packets on an
interface. It ranges from 1 to 8192 seconds. By default, the value is 1 second.
hello
seconds
: Specifies the interval for sending Hello packets on an interface. It
ranges from 1 to 8,192 (in seconds). This value must equal the
hello
seconds
value of
the router virtually linked to the interface. By default, the value is 10 seconds.
simple
password:
Specifies the simple text authentication password, not exceeding 8
characters, of the interface. This value must equal the authentication key of the virtually
linked peer.
keyid:
Specifies the MD5 authentication key ID. Its value
ranges from 1 to 255. It must
be equal to the authentication key ID of the virtually linked peer.
key
:
Specifies the
MD5 authentication key. If it is input in a plain text form, MD5
key
is a
character string in the range 1 to 16 characters. It will be displayed in a cipher text form
in a length of 24 characters when the
display current-configuration
command is
executed. Inputting the MD5
key
in a cipher text form with 24 characters is also
supported.
Description
Use the
vlink-peer
command to create and configure a virtual link.
Use the
undo vlink-peer
command to cancel an existing virtual link.
According to RFC2328, the OSPF area should be connected with the backbone
network. You can use the
vlink-peer
command to keep the connectivity. Virtual link can
be regarded as a common OSPF-enabled interface so that you can easily understand
why to configure the parameters such as Hello, retransmit, and trans-delay on it.
One thing should be mentioned. When configuring virtual link authentication, the
authentication-mode
command is used to set the authentication mode as MD5 cipher
text or simple text on the backbone network.
