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.
OSPFv3 does not send the packet if it fails to obtain a valid send key.
2. Uses the key ID, authentication algorithm, and key string to authenticate the packet.
If the key ID is greater than 65535, OSPFv3 does not send the packet.
When keychain authentication is configured for an OSPFv3 virtual link, OSPFv3 performs the
following operations after receiving a packet:
1. Uses the key ID carried in the packet to obtain a valid accept key from the keychain.
OSPFv3 discards the packet if it fails to obtain a valid accept key.
2. Uses the authentication algorithm and key string for the valid accept key to authenticate the
packet.
If the authentication fails, OSPFv3 discards the packet.
OSPFv3 supports only the HMAC-SHA-256 authentication algorithm.
The ID of keys used for authentication can only be in the range of 0 to 65535.
