ipv6 ospf authentication

Enable IPv6 OSPF on an interface.

Syntax

ipv6 ospf authentication {null | ipsec spi number {MD5 | SHA1} [ key-encryption-type] key}}

To remove an IPsec authentication policy from an interface, use 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, use the no ipv6 ospf authentication null command.

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.
