Use this command to create a virtual link or set its parameters. Use the no form of this command to
restore the default setting.

no area area-id virtual-link router-id [ hello-interval ] [ dead-interval ] [ retransmit-interval ]
[ transmit-delay ] [ instance ] [ authentication ] [ encryption ]
ID of the area in which the virtual link is located.
It can be an integer or an IPv6 prefix.
Neighbor router ID of the virtual link.
Sets the interval to send the hello message on the local virtual link
interface in the range from 1 to 65535 in the unit of seconds.
Interval for the local interface of the virtual link to wait before
considering that the neighbor fails.
It is in the range from 1 to 65535 in the unit of seconds.
retransmit-interval seconds
Interval for retransmitting LSA on the local interface of the virtual link .
The range is from 1 to 65535 in the unit of seconds.
Delay on the local interface of the virtual link in sending LSA.
The range is from 1 to 65535 in the unit of seconds.
Specifies the instance corresponding to the virtual link. No virtual link
can be established between different instances. Range: 0.-255
authentication ipsec spi
spi [ md5 | sha1 ] [ 0 | 7 ] key
Specifies OSPFv3 authentication.
Authentication configuration on two neighboring devices must
be consistent. The service password-encryption command
enables a key to be displayed in the cipher-text format.
spi specifies a security parameter index, in the range from 256 to
4294967295.
md5 specifies the MD5 authentication mode.
sha1 specifies the SHA1 authentication mode.
0 indicates that a key is displayed in the plain-text format.
7 indicates that a key is displayed in the cipher-text format.
key specifies an authentication key.
encryption ipsec spi spi
esp null [ md5| sha1 ] [ 0|7 ]
key
Specifies OSPFv3 encryption authentication.
Authentication configuration on two neighboring devices must
be consistent. The service password-encryption command
enables a key to be displayed in the cipher-text format.
