To display the configuration of IPsec authentication policies on the router, enter the show crypto ipsec
policy command.
Configuring IPsec Encryption for an OSPFv3 Area
Prerequisite : Before you enable IPsec encryption in an OSPFv3 area, you must first enable OSPFv3
globally on the router (see Configuration Task List for OSPFv3 (OSPF for IPv6) on page 726 ).
To configure IPsec encryption in an OSPFv3 area, enter the following command in global configuration
mode:
An SPI value must be unique to one IPsec security policy (authentication or encryption) on the router. You
must configure the same encryption policy (same SPI and keys) on each interface in an OPSFv3 link.

ROUTER-OSPF Enable IPsec encryption for OSPFv3 packets in an area,
where:
area
area-id
specifies the area for which OSPFv3
traffic is to be encrypted. For
area-id
, you can enter
a number or an IPv6 prefix.
spi
number
is the Security Policy index (SPI) value.
Range: 256 to 4294967295.
esp
encryption-algorithm
specifies the 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
specifies the text string
used in the encryption.
All neighboring OSPFv3 routers must share the same key
to decrypt information. 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.
key-encryption-type
(optional) specifies if the key
is encrypted. Valid values: 0 (key is not encrypted)
or 7 (key is encrypted).
authentication-algorithm
specifies the
authentication algorithm to use for encryption.
Valid values are MD5
or
SHA1.
key
specifies the text string
used in authentication.
All neighboring OSPFv3 routers must share the same key
to exchange information.
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).
key-authentication-type
(optional) specifies if the
authentication key is encrypted. Valid values: 0 or
7
