IKEv1 and IKEv2 on same Router

[henokk601]

Hi All 

I have cisco 3941 Router and running multiple site to site IPsec VPNs and they are running IKEv1 and now I want to configure IKEv2 for one customer before doing the configuration I want to know if it has an impact on the previous site to site VPNs. Does it affect the IKEv1 VPNs please any advice?

No issue just config ISAKMP profile for new IKEv2.

@henokk601 you can run both IKEv1 and IKEv2 at the same time, without a problem.

You just need to configure the relevant IKEv2 profile to match on the remote peer to identify correctly.

Hi Rob,

Can I use the same crypto map for both ikev1 and ikev2 and apply it on the interface?
