IKEv2 Option Description
NOTE
Not supported for NI R05.8.00 release.
Configuring the IKEv2 Proposal
IKEv2 Proposal sets the configurable parameters which are exchange during IKEv2 peer negotiation during the first phase.
The default IKEv2 proposal requires no configuration and its parameters are as follows:
Encryption: aes-cbc-256
PRF: sha384
Integrity: sha384
dh-group: 20
This default IKEv2 proposal will be known as ikev2-default-proposal.
The following commands are available to configure the proposals manually, if you do not want to use the default proposal.
NOTE
The default proposal command will only be available if additional cryptographic algorithms are supported, as currently there is
no requirement to support them in NI Release 5.8.00.

dhgroup {1} {2} {5} {14} {15} {16}
{19} {20} {24}
Group used for Diffie-Hellman negotiations. Allowed values are:
1 — 768-bit DH
2 — 1024-bit DH
5 — 1536-bit DH
14 — Specifies the 2048-bit DH group.
15 — Specifies the 3072-bit DH group.
16 — Specifies the 4096-bit DH group.
19 — Specifies the 256-bit elliptic curve DH (ECDH) group.
20 — Specifies the 384-bit ECDH group.
24 — Specifies the 2048-bit DH/SA group.
NOTE
For the first release, only DH-group 14, 19, and 20 will be supported. Support for other DH groups will
be considered for inclusion in the next major release.
prf { sha384 | sha256 } Hash algorithm to be used to generate key material for IKE SA negotiation. Multiple algorithms may be specified,
separated by commas.
encryption {3des} {aes-cbc-128}
{aes-cbc-192} {aes-cbc-256}
Encryption algorithm to be used to protect IKEv2 data. Multiple algorithms may be specified. Allowed values are:
3des
aes-cbc-128
aes-cbc-192
aes-cbc-256
NOTE
For the first release, only aes-cbc-128 and aes-cbc-256 will be supported. Support for other
encryption for IKEv2 will be considered for inclusion in the next major release.
