•
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 the keyword TenGigabitEthernet then the slot/port[/
subport] information.
•
For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
•
For a port channel interface, enter the keywords port-channel then a number.
•
For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
