Users Guide
• key: species 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) species if the key is encrypted. Valid values: 0 (key is not encrypted) or 7 (key is
encrypted).
• authentication-algorithm: species the authentication algorithm to use for encryption. The valid values are MD5 or SHA1.
• key: species 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) species if the authentication key is encrypted. The valid values are 0 or 7.
• Remove an IPsec encryption policy from an OSPFv3 area.

Displaying OSPFv3 IPsec Security Policies
To display the conguration of IPsec authentication and encryption policies, use the following commands.
• Display the AH and ESP parameters congured in IPsec security policies, including the SPI number, key, and algorithms used.
EXEC Privilege mode
show crypto ipsec policy [name name]
• name: displays conguration details about a specied 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 specic 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.
