Configuring IPsec Authentication on an Interface
To configure, remove, or display IPsec authentication on an interface, use the following commands.
Prerequisite: Before you enable IPsec authentication on an OSPFv3 interface, first enable IPv6 unicast routing globally, configure an
IPv6 address and enable OSPFv3 on the interface, and assign it to an area (refer to
IPv6)).
The SPI value must be unique to one IPsec security policy (authentication or encryption) on the router. Configure the same
authentication policy (the same SPI and key) on each OSPFv3 interface in a link.
• Enable IPsec authentication for OSPFv3 packets on an IPv6-based interface.
INTERFACE mode
ipv6 ospf authentication {null | ipsec spi number {MD5 | SHA1} [key-encryption-type] key}
– null: causes an authentication policy configured for the area to not be inherited on the interface.
– ipsec spi number: the security policy index (SPI) value. The range is from 256 to 4294967295.
– MD5 | SHA1: specifies the authentication type: Message Digest 5 (MD5) or Secure Hash Algorithm 1 (SHA-1).
– key-encryption-type: (optional) specifies if the key is encrypted. The valid values are 0 (key is not encrypted) or 7
(key is encrypted).
– 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).
• Remove an IPsec authentication policy from an interface.
no ipv6 ospf authentication ipsec spi number
• Remove null authentication on an interface to allow the interface to inherit the authentication policy configured for the OSPFv3
area.
no ipv6 ospf authentication null
• Display the configuration of IPsec authentication policies on the router.

• Display the security associations set up for OSPFv3 interfaces in authentication policies.

Configuring IPsec Encryption on an Interface
To configure, remove, or display IPsec encryption on an interface, use the following commands.
Prerequisite: Before you enable IPsec encryption on an OSPFv3 interface, first enable IPv6 unicast routing globally, configure an
IPv6 address and enable OSPFv3 on the interface, and assign it to an area (refer to
IPv6)).
NOTE: When you configure encryption using the ipv6 ospf encryption ipsec command, you enable both IPsec
encryption and authentication. However, when you enable authentication on an interface using the ipv6 ospf
authentication ipsec command, you do not enable encryption at the same time.
The SPI value must be unique to one IPsec security policy (authentication or encryption) on the router. Configure the same
authentication policy (the same SPI and key) on each OSPFv3 interface in a link.
• Enable IPsec encryption for OSPFv3 packets on an IPv6-based interface.
