Area for which OSPFv3 traffic is to be encrypted. For area-id,
enter a number.
The range is from 0 to 4294967295.
Security Policy index (SPI) value that identifies an IPsec
security policy.
The range is from 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).
