ipv6 ospf authentication
Configure an IPsec authentication policy for OSPFv3 packets on an IPv6 interface.
Syntax
ipv6 ospf authentication {null | ipsec spi number {MD5 | SHA1} [key-encryption-
type] key}}
Parameters
null Causes an authentication policy configured for the area to not be inherited on the
interface.
ipsec spi number Security Policy index (SPI) value that identifies an IPsec security policy. The range is from
256 to 4294967295.
MD5 | SHA1
Authentication type: Message Digest 5 (MD5) or Secure Hash Algorithm 1 (SHA-1).
key-encryption-
type
(OPTIONAL) Specifies if the key is encrypted.
Valid values: 0 (key is not encrypted) or 7 (key is encrypted).
key
Text string used in authentication.
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).
Defaults Not configured.

Usage Information
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 the interface to an area.
An SPI value must be unique to one IPsec security policy (authentication or encryption) on the router. Configure
the same authentication policy (same SPI and key) on each OSPFv3 interface in a link.
To remove an IPsec authentication policy from an interface, enter the no ipv6 ospf authentication spi number
command. To remove null authentication on an interface to allow the interface to inherit the authentication policy
configured for the OSPFv3 area, enter the no ipv6 ospf authentication null command.
