IKE & IPSec

Hi,

I have configured VPN a site to site vpn between two routers. In the IKE policy cryption type is DES (which is by default), whearas in the IPSec transform set I am defining encryption type as 3DES, but I can see in the "sh crypto ipsec sa" that encryption is working fine for days. I thought if there is a mismatch in IKE & IPSec policies it won't work. But its working. Can anyone please explain? Thanks.

Re: IKE & IPSec

Hi

IKE policies are matched between the peers and negotiated then it creates the ipsec security associations.
