area encryption

Configure an IPsec encryption policy for OSPFv3 packets in an OSPFv3 area.

Syntax

area area-id encryption ipsec spi number esp encryption-algorithm [key-encryption-type] key authentication-algorithm [key-encryption-type] key | null

To remove an IPsec encryption policy from an interface, use the no area area-id encryption spi number command.

Parameters

area area-id	Area for which OSPFv3 traffic is to be encrypted. For area-id, 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.
esp encryption-algorithm	Encryption algorithm used with ESP. Valid values are: 3DES, DES, AES-CBC, and NULL. For AES-CBC, only the AES-128 and AES-192 ciphers are supported.
key-encryption-algorithm	(OPTIONAL) Specifies if the key is encrypted. Valid values: 0 (key is not encrypted) or 7 (key is encrypted).
key	Text string used in encryption. The required lengths of a non-encrypted or encrypted key are: 3DES - 48 or 96 hex digits; DES - 16 or 32 hex digits; AES-CBC -32 or 64 hex digits for AES-128 and 48 or 96 hex digits for AES-192.
authentication-algorithm	Specifies the authentication algorithm to use for encryption. Valid values are `MD5` or `SHA1`.
key-encryption-type	(OPTIONAL) Specifies if the authentication 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).
null	Causes an encryption policy configured for the area to not be inherited on the interface.

Defaults

Not configured.

Usage Information

Before you enable IPsec encryption on an OSPFv3 interface, first enable OSPFv3 globally on the router. Configure the same encryption policy (same SPI and keys) on each interface in an OSPFv3 link.

An SPI value must be unique to one IPsec security policy (authentication or encryption) on the router.

When you configure encryption for an OSPFv3 area with the area encryption command, you enable both IPsec encryption and authentication. However, when you enable authentication on an area with the area authentication command, you do not enable encryption at the same time.

If you have enabled IPsec authentication in an OSPFv3 area with the area authentication command, you cannot use the area encryption command in the area at the same time.

The configuration of IPsec encryption on an interface-level takes precedence over an area-level configuration. If you remove an interface configuration, an area encryption policy that has been configured is applied to the interface.
