MD5 | SHA1
Authentication type: Message Digest 5 (MD5) or Secure Hash
Algorithm 1 (SHA-1).
key-encryption-
type
(OPTIONAL) Specifies if the key is encrypted.
Valid values: 0 (key is not encrypted) or 7 (key is encrypted).
key
Text string used in authentication.
For MD5 authentication, the key must be 32 hex digits (non-
encrypted) or 64 hex digits (encrypted).
For SHA-1 authentication, the key must be 40 hex digits (non-
encrypted) or 80 hex digits (encrypted).
Defaults Not configured.

Usage
Information
Before you enable IPsec authentication on an OSPFv3 interface, you must first enable IPv6
unicast routing globally, configure an IPv6 address and enable OSPFv3 on the interface, and
assign the interface to an area.
An SPI value must be unique to one IPsec security policy (authentication or encryption) on the
router. You must configure the same authentication policy (same SPI and key) on each OSPFv3
interface in a link.
To remove an IPsec authentication policy from an interface, enter the no ipv6 ospf
authentication spi
number
command. To remove null authentication on an interface to allow
the interface to inherit the authentication policy configured for the OSPFv3 area, enter the no
ipv6 ospf authentication null command.
