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.

Examples of the show crypto ipsec Commands

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.
