area encryption e t 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 Parameters area area-id ipsec spi number esp encryption-algorithm key-encryption-type key authentication-algorith m key-encryption-type key null Area for which OSPFv3 traffic is to be encrypted. For area-id, you can enter a number or an IPv6 prefix. Security Policy index (SPI) value that identifies an IPsec security policy. Range: 256 to 4294967295. 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. (OPTIONAL) Specifies if the key is encrypted. Valid values: 0 (key is not encrypted) or 7 (key is encrypted). 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. Specifies the authentication algorithm to use for encryption. Valid values are MD5 or SHA1. (OPTIONAL) Specifies if the authentication key is encrypted. Valid values: 0 (key is not encrypted) or 7 (key is encrypted). 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). Causes an encryption policy configured for the area to not be inherited on the interface. Default Not configured. Command Modes ROUTER OSPFv3 Command History Version 8.4.2.0 Introduced Usage Information Before you enable IPsec encryption on an OSPFv3 interface, you must first enable OSPFv3 globally on the router. You must 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. Note that 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.
