Usage
Information
Before you enable IPsec encryption on an OSPFv3 interface, first enable OSPFv3 globally on the router.
Configure the same encryption policy (same SPI and keys) on each interface in an OSPFv3 link.
An SPI value must be unique to one IPsec security policy (authentication or encryption) on the router.
When you configure encryption for an OSPFv3 area with the area encryption command, you enable
both IPsec encryption and authentication. However, when you enable authentication on an area with the
area authentication command, you do not enable encryption at the same time.
If you have enabled IPsec authentication in an OSPFv3 area with the area authentication
command, you cannot use the area encryption command in the area at the same time.
The configuration of IPsec encryption on an interface-level takes precedence over an area-level
configuration. If you remove an interface configuration, an area encryption policy that has been
configured is applied to the interface.
To remove an IPsec encryption policy from an interface, enter the no area area-id encryption spi number
command.

● show crypto ipsec policy – display the configuration of IPsec encryption policies.
area nssa
Specify an area as a not so stubby area (NSSA).
Syntax
area area-id nssa [default-information-originate] [no-redistribution] [no-
summary]
To delete an NSSA, use the no area area-id nssa command.
Parameters
area-id Specify the OSPF area by entering a number from zero (0) to 65535.
no-redistribution (OPTIONAL) Specify that the redistribute command does not distribute
routes into the NSSA. This command can be used when the router is an
autonomous system boundary router (ASBR) or area border router (ABR).
default-

originate
(OPTIONAL) Allows external routing information to be imported into the NSSA by
using Type 7 default.
no-summary (OPTIONAL) Specify that no summary LSAs should be sent into the NSSA.
Defaults Not configured.
