Usage guidelines
You can configure a virtual link to maintain connectivity between a non-backbone area and the
backbone, or maintain connectivity within the backbone. A virtual link is similar to an interface with
OSPFv3 enabled. You can configure parameters such as
trans-delay
Both ends of a virtual link must be ABRs that are configured with the
The following guidelines apply to parameters:
•
The smaller the hello interval is, the faster the network converges, and the more network
resources are consumed.
•
For a low speed link, set a large retransmission interval to avoid unnecessary retransmissions.
•
Specify a transmission delay with the
delay.
The authentication mode specified for an OSPFv3 virtual link has a higher priority than the mode
specified for the backbone area. If no authentication mode is specified for the virtual link, the mode
specified for the backbone area applies.
When keychain authentication is configured for an OSPFv3 virtual link, OSPFv3 performs the
following operations before sending a packet:
1. Obtains a valid send key from the keychain.
