This mode consumes more system resources when multiple data flows exist between two
subnets to be protected.
Application-based IPsec
This IPsec implementation method does not require an ACL. All packets of the application bound to
an IPsec profile are encapsulated with IPsec, and all packets of the applications that are not bound
with IPsec and the IPsec packets that failed to be de-encapsulated are dropped.
You can use IPsec to protect an IPv6 routing protocol by using this method. The supported IPv6
routing protocols include OSPFv3, IPv6 BGP, and RIPng.
In one-to-many communication scenarios, you must configure the IPsec SAs for an IPv6 routing
protocol in manual mode because of the following reasons:
•
The automatic key exchange mechanism is used only to protect communications between two
points. In one-to-many communication scenarios, automatic key exchange cannot be
implemented.
•
One-to-many communication scenarios require that all the devices use the same SA
parameters (SPI and key) to receive and send packets. IKE negotiated SAs cannot meet this
requirement.

FIPS compliance

The device supports the FIPS mode that complies with NIST FIPS 140-2 requirements. Support for
features, commands, and parameters might differ in FIPS mode (see "Configuring FIPS") and
non-FIPS mode.

IPsec tunnel establishment

IPsec tunnels can be established in different methods. Choose a correct method to establish IPsec
tunnels according to your network conditions:
•
ACL-based IPsec tunnel—Protects packets identified by an ACL. To establish an ACL-based
IPsec tunnel, configure an IPsec policy, reference an ACL in the policy, and apply the policy to
an interface (see
the same in an IPv4 network and in an IPv6 network.
•
Application-based IPsec tunnel—Protects the packets of an application. This method can be
used to protect IPv6 routing protocols. It does not require an ACL. To establish
application-based IPsec tunnels, configure manual IPsec profiles and bind the profiles to an
IPv6 routing protocol. For more information about IPv6 routing protocols, see

protocols."
