Information
Before you enable IPsec encryption 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 encryption policy (same SPI and keys) on each OSPFv3 interface in a
link.
To remove an IPsec encryption policy from an interface, enter the no ipv6 ospf encryption 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 encryption null
command.

The required lengths of a non-encrypted or encrypted key are:
3DES - 48 or 96 hex digits; DES - 16 or 32 hex digits; AES-CBC -
32 or 64 hex digits for AES-128 and 48 or 96 hex digits for AES-192.

For MD5 authentication, the key must be 32 hex digits (non-encrypted) or 64
hex digits (encrypted).
