Default level
2: System level
Parameters
router-id: Router ID of the neighbor on the virtual link.
hello seconds: Hello interval in seconds, in the range of 1 to 8192. The default is 10. It must be
identical to the hello interval on the virtual link neighbor.
retransmit seconds: Retransmission interval in seconds, in the range of 1 to 3600. The default is 5.
trans-delay seconds: Transmission delay interval in seconds, in the range of 1 to 3600. The default
is 1.
dead seconds: Dead interval in seconds, in the range of 1 to 32768. The default is 40. It must be
identical to that on the virtual link neighbor. The dead interval is at least four times the hello interval.
md5: MD5 authentication.
hmac-md5: HMAC-MD5 authentication.
simple: Simple authentication.
key-id: Key ID for MD5 or HMAC-MD5 authentication, in the range of 1 to 255.
ciper: Sets a ciphertext password.
plain: Sets a plaintext password.
password: Sets the authentication password. This argument is case sensitive. For simple
authentication mode, it is a plaintext string of 1 to 8 characters, or a ciphertext string of 1 to 41
characters. For MD5/HMAC-MD5 authentication mode, it is a plaintext string of 1 to 16 characters, or
a ciphertext string of 1 to 53 characters.
Description
Use vlink-peer to configure a virtual link.
Use undo vlink-peer to remove a virtual link.
As defined in RFC 2328, all non-backbone areas must maintain connectivity to the backbone. You
can use the vlink-peer command to configure a virtual link to connect an area to the backbone.
Considerations on parameters:
•
The smaller the hello interval is, the faster the network converges and the more network
resources are consumed.
•
A so small retransmission interval will lead to unnecessary retransmissions. A big value is
appropriate for a low speed link.
•
You need to specify an appropriate transmission delay with the trans-delay keyword.
The authentication mode at the non-backbone virtual link end follows the one at the backbone virtual
link end. The two authentication modes (MD5 or Simple) are independent, and you can specify
neither of them.
The authentication password, set in either text or cipher text, is saved to the configuration file in
cipher text.
If neither cipher nor plain is specified, cipher applies to the MD5/HMAC-MD5 authentication mode
and plain applies to the simple authentication mode, by default.
