Parameter
router-id: Router ID of virtual link neighbor.
hello seconds: Interval that router transmits hello message. It ranges from 1 to 8192
seconds. This value must equal the hello seconds value of the router virtually linked to
the interface. By default, the value is 10 seconds,
retransmit seconds: Specifes the interval for re-transmitting the LSA packets on an
interface. It ranges from 1 to 8192 seconds. By default, the value is 5 seconds.
trans-delay seconds: Specifes the interval for delaying transmitting LSA packets on an
interface. It ranges from 1 to 8192 seconds. By default, the value is 1 second.
dead seconds: Specifies the interval of death 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 4 times of the hello seconds. By default, the value is 40 seconds.
simple password: Specifies the simple text authentication key, not exceeding 8
characters, of the interface. This value must equal the authentication key of the virtually
linked neighbor.
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 neighbor.
key: Specifies the authentication key on an interface. It is a character string not
exceeding 16 characters. This value must equal the authentication key of the virtually
linked neighbor. And the key will be displayed in a cipher text form in a length of 24
characters when display current-configuration command is executed. Inputting the
key in a cipher text form with 24 characters long 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 vlink-peer command to keep the connectivity. Virtual link
somewhat can be regarded as a common ospf enabled interface so that you can easily
