Open Shortest Path First (OSPFv2 and OSPFv3)
Version 7.4.1.0
Introduced
Configure an IPsec authentication policy for OSPFv3 packets on an IPv6 interface.

INTERFACE
Version 8.4.2.0
Introduced
Before you enable IPsec authentication on an OSPFv3 interface, you must 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.
You must 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.
area authentication
show crypto ipsec policy
show crypto ipsec sa ipv6
Causes an authentication policy configured for the area to not be inherited on the
interface.
Security Policy index (SPI) value that identifies an IPsec security policy.
Range: 256 to 4294967295.
Authentication type: Message Digest 5 (MD5) or Secure Hash Algorithm 1
(SHA-1).
(OPTIONAL) Specifies if the key is encrypted.
Valid values: 0 (key is not encrypted) or 7 (key is encrypted).
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).
