Information
Before you enable IPsec authentication on an OSPFv3 area, you must first enable OSPFv3 globally on
the router. You must configure the same authentication policy (same SPI and key) on each interface in
an OSPFv3 link.
An SPI number must be unique to one IPsec security policy (authentication or encryption) on the
router.
If you have enabled IPsec encryption in an OSPFv3 area with the area encryption command, you
cannot use the area authentication command in the area at the same time.
The configuration of IPsec authentication on an interface-level takes precedence over an area-level
configuration. If you remove an interface configuration, an area authentication policy that has been
configured is applied to the interface.
To remove an IPsec authentication policy from an OSPFv3 area, enter the no area area-id
authentication spi number command.

Commands
area area-id
Area for which OSPFv3 traffic is to be authenticated. For area-id, you can enter
a number or an IPv6 prefix.
ipsec spi number
Security Policy index (SPI) value that identifies an IPsec security policy.
Range: 256 to 4294967295.
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).
