ipv6 ospf authentication
Configure an IPsec authentication policy for OSPFv3 packets on an IPv6 interface.
S4820T
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.
