H3C S6550X-HI Series Command Reference Manual page 1938

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 area, 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.

Usage guidelines
You can configure an OSPFv3 cost for an interface with one of the following methods:
•
Configure the cost value in interface view.
•
Configure a bandwidth reference value. OSPFv3 computes the cost automatically based on the
bandwidth reference value by using the following formula: Interface OSPFv3 cost = Bandwidth
reference value / Interface bandwidth.
If the calculated cost is greater than 65535, the value of 65535 is used.

If the calculated cost is smaller than 1, the value of 1 is used.

to set a reference bandwidth value for link cost calculation.
to restore the default.
