Usage Information
Before you enable IPsec encryption on an OSPFv3 interface, rst enable IPv6 unicast routing globally,
congure 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.
Congure 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 congured for the OSPFv3 area, enter the no ipv6 ospf no ipv6 ospf
encryption null command.
