•
key: specifies the text string used in the encryption. All neighboring OSPFv3 routers must share the
same key to decrypt information. 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.
•
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. The
valid values are MD5 or SHA1.
•
key: specifies the text string used in authentication. All neighboring OSPFv3 routers must share 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. The valid
values are 0 or 7.

Displaying OSPFv3 IPsec Security Policies
To display the configuration of IPsec authentication and encryption policies, use the following commands.
•
Display the AH and ESP parameters configured in IPsec security policies, including the SPI number, key,
and algorithms used.
EXEC Privilege mode
show crypto ipsec policy [name name]
•
name: displays configuration details about a specified policy.
•
Display security associations set up for OSPFv3 links in IPsec authentication and encryption policies on the
router.
EXEC Privilege
show crypto ipsec sa ipv6 [interface interface]
To display information on the SAs used on a specific interface, enter interface interface, where
interface is one of the following values:
•
For a 10-Gigabit Ethernet interface, enter TenGigabitEthernet slot/port.
•
For a Port Channel interface, enter port-channel number.
•
For a 40-Gigabit Ethernet interface, enter FortyGigabitEthernet slot/port.
•
For a VLAN interface, enter vlan vlan-id. The valid VLAN IDs are from 1 to 4094.
