CLI Guide

An SPI value must be unique to one IPsec security policy (authentication or
encryption) on the router. Configure the same encryption policy (same SPI and key)
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 no ipv6 ospf encryption null
command.
