○ 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.
● Remove an IPsec encryption policy from an OSPFv3 area.
no area area-id encryption ipsec spi number
● Display the configuration of IPsec encryption policies on the router.

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 25-Gigabit Ethernet interface, enter the keyword twentyFiveGigE then the slot/port[/subport] information.
○ For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port/subport information.
○ For a 50-Gigabit Ethernet interface, enter the keyword fiftyGigE then the slot/port/subport information.
○ For a 100-Gigabit Ethernet interface, enter the keyword hundredGigE 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.
In the first example, the keys are not encrypted (shown in bold). In the second and third examples, the keys are encrypted
(shown in bold).
The following example shows the show crypto ipsec policy command.
