md5: MD5 authentication.
hmac-md5: HMAC-MD5 authentication.
simple: Simple authentication.
key-id: Key ID for MD5 or HMAC-MD5 authentication, in the range 1 to 255.
plain | cipher: Plain or cipher type. If plain is specified, only a plain password can be input, and the
password is displayed in plain text upon displaying the configuration file. If cipher is specified, either a
plain or a cipher password can be input, and the password is displayed in cipher text upon displaying
the configuration file. By default, MD5 and HMAC-MD5 support cipher password, and simple
authentication supports plain password.
password: Plain or cipher password. Simple authentication: For plain type, a plain password is a string
of up to 8 characters. For cipher type, a plain password is a string of up to 8 characters, and a cipher
password is a string of up to 24 characters. MD5/HMAC-MD5 authentication: For plain type, a plain
password is a string of up to 16 characters. For cipher type, a plain password is a string of up to 16
characters, and a cipher password is a string of up to 24 characters.
Description
Use the vlink-peer command to configure a virtual link.
Use the undo vlink-peer command 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.
