Configuring OSPFv3 authentication
OSPFv3 uses keychain authentication to prevent routing information from being leaked and routers
from being attacked.
OSPFv3 adds the Authentication Trailer option into outgoing packets, and uses the authentication
information in the option to authenticate incoming packets. Only packets that pass the authentication
can be received. If a packet fails the authentication, the OSPFv3 neighbor relationship cannot be
established.
The authentication mode specified for an OSPFv3 interface has a higher priority than the mode
specified for an OSPFv3 area.
