Networking OS Command Line Reference Guide.
The following is a list of the Dell Networking OS version history for this command.
Version Description
9.1.(0.0) Introduced on the S4810 and Z9000.
8.3.19.0 Introduced on the S4820T.
8.4.2.0 Introduced on the E-Series TeraScale.
Usage Information Before you enable IPsec authentication on an OSPFv3 area, you must rst enable OSPFv3 globally on the
router. Congure the same authentication policy (same SPI and key) on each interface in an OSPFv3 link.
An SPI number must be unique to one IPsec security policy (authentication or encryption) on the router.
If you have enabled IPsec encryption in an OSPFv3 area with the area encryption command, you
cannot use the area authentication command in the area at the same time.
The conguration of IPsec authentication on an interface-level takes precedence over an area-level
conguration. If you remove an interface conguration, an area authentication policy that has been
congured is applied to the interface.
To remove an IPsec authentication policy from an OSPFv3 area, enter the no area area-id
authentication spi number command.
