area authentication
Configure an IPsec authentication policy for OSPFv3 packets in an OFSPFv3 area.
Syntax
area area-id authentication ipsec spi number {MD5 | SHA1} [key-encryption-
type] key
Parameters
area area-id
Area for which OSPFv3 traffic is to be authenticated. For area-id, you can enter a
number.
The range is from 0 to 4294967295.
ipsec spi number
Security Policy index (SPI) value that identifies an IPsec security policy.
The range is from 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.
The values are 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 area, you must first enable OSPFv3 globally on the
router. 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.
