– authentication-algorithm: species the authentication algorithm to use for encryption. The valid values are MD5 or
SHA1.
– key: species 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) species if the authentication key is encrypted. The valid values are 0 or 7.
• Remove an IPsec encryption policy from an OSPFv3 area.

• Display the conguration of IPsec encryption policies on the router.

Displaying OSPFv3 IPsec Security Policies
To display the conguration of IPsec authentication and encryption policies, use the following commands.
• Display the AH and ESP parameters congured in IPsec security policies, including the SPI number, key, and algorithms used.
EXEC Privilege mode
show crypto ipsec policy [name name]
– name: displays conguration details about a specied 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 specic 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 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.
Examples of the show crypto ipsec Commands
In the rst 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.
