I have a Cisco 2911 configured with a site-to-site VPN connection to a Cisco ASA firewall using IKEv2, the IPSec tunnel is failing to come up and when i check the output of the "show crypto ipsec sa " it is indicating as if PFS and DH group are not enabled while in the configuratio they are defined, this is evidenced in the output of the "show crypto map" command, see outputs below To view the list of possible set commands that you can do in a crypto map, use the help function.

Alternatively, it asks that IPSec requires PFS when requests are received for new security associations. To specify that IPSec not request PFS, issue the no crypto map set pfs command.

If we would apply the Crypto Map to the tunnel we would do encryption first and GRE second, which translates into a Proxy ACL that needs to match end to end traffic flows. This over complicates the design. Figure 5 .

Group 7, where the elliptical curve field size is 163 bits, is designed for the faster computation of keys usually used by the handheld PCs. Group 5 is the most secure technique but requires more processing overhead. The syntax to configure PFS is. crypto map map-name seq-num set pfs {group1 | group2 | group5 | group7} it is Optional Command

DHGroup2048 & PFS2048 are the same as Diffie-Hellman Group 14 in IKE and IPsec PFS. See Diffie-Hellman Groups for the complete mappings.; For GCMAES algorithms, you must specify the same GCMAES algorithm and key length for both IPsec Encryption and Integrity.

If you have multiple S2S VPN tunnels, you have to use the same crypto-map with different priority numbers.
