Command Manual – Routing Protocol
Quidway S3900 Series Ethernet Switches-Release 1510
Chapter 3 OSPF Configuration Commands
Huawei Technologies Proprietary
3-55
Parameter
route-id
: Router ID of virtual link peer.
hello seconds
: Specifies the interval, in seconds, at which the router transmits hello
packet. It ranges from 1 to 8192 and defaults to 10. This value must equal the
hello
seconds
value of the router virtually linked to the interface.
retransmit seconds:
Specifies the interval, in seconds, for retransmitting the LSA
packets on an interface. It ranges from 1 to 8192 and defaults to 5.
trans-delay
seconds:
Specifies the delay, in seconds, for transmitting LSA packets on
an interface. It ranges from 1 to 8192 and defaults to 1.
dead seconds
: Specifies the interval, in seconds, of death timer. It ranges from 1 to
8192 and defaults to 40. This value must equal the
dead
seconds
of the router virtually
linked to it and must be at least four times of the hello
seconds
.
simple
password:
Specifies the simple text authentication password, which contains up
to eight characters, of the interface. This value must equal the authentication key of the
virtually linked peer.
keyid:
MD5 authentication key ID. It ranges from 1 to 255. It must be equal to the
authentication key ID of the virtually linked peer.
key
:
MD5 authentication key. If you use simple text authentication key, you can input a
string containing 1 to 16 characters. When you use the
display current-configuration
command to display system information, the MD5 authentication key is displayed in the
form of cipher text with a length of 24 characters. Inputting the
key
in the form of cipher
text with a length of 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, an OSPF area must be connected to the backbone network.
You can use the
vlink-peer
command to keep the connectivity. Virtual link can be
regarded as a common interface that uses OSPF because the principle for configuring
the parameters such as hello, retransmit, and trans-delay on it is similar.
Note that, when configuring virtual link authentication, you use the
authentication-mode
command to specify the authentication mode as MD5 cipher
text or simple text on the backbone network.
Related command:
authentication-mode, display ospf
.
Example
# Create a virtual link to 10.110.0.3 and use the MD5 cipher authentication mode.
