IPV6 IPSEC Site-to-Site issue

[sakatzidisgiwrgos]

Hello community,

I have an issue while i am trying to configure a Site-to-Site VPN with crypto maps with IPV6.

The topology is uploaded as an attachment.

I noticed that when i apply my crypto map on the outside interfaces on the routers, i get this message: 

%CRYPTO-4-RECVD_PKT_NOT_IPSEC_V6: Rec'd packet not an IPSEC packet. (ip) vrf/dest_addr= /FF02::1, src_addr= FE80::C803:3BFF:FED8:1C, prot= 58

The configuration of each router is uploaded also.

In addition, on R3 i can see some error messages regarding ipv6:

1 20:24:32.963: ICMPv6: Sent Unreachable code 3, src=2001:DB8:0:1::2, Dst=2001:DB8:0:1::1
*Nov 1 20:24:32.967: ICMPv6: Sent N-Solicit, src=2001:DB8:0:1::2, Dst=FF02::1:FF00:1
R3#
*Nov 1 20:24:34.055: ICMPv6: Sent N-Solicit, src=2001:DB8:0:1::2, Dst=FF02::1:FF00:1
R3#
*Nov 1 20:24:35.143: ICMPv6: Sent N-Solicit, src=2001:DB8:0:1::2, Dst=FF02::1:FF00:1

The result is that the IPSec tunnel cannot be established.

Any help would be appreciated

Thanks in advance.

Hopefully the link @MHM Cisco World provided will help explain it for you but let's clarify some info about what you're trying to do:
- which routers are you trying to create the IPSEC tunnel between?  R1 & R2?
- you've provided config for R1 & R2 but not R3?

Are you aware that crypto maps are being deprecated?  Latest IOS already doesn't support crypto map on some interfaces and Cisco plan to discontinue support for crypto maps altogether:
