I have to convert one of my client DMVPN setups with 78 remote sites using a pre shared key to some kind of certificates. I want to be able to revoke certificate if needed, and also i want to be in charge of approviing certificate requests.
this is needed in case of my client needs to hire a consultant to replace the router (DMVPN Spoke) he does not want him to have any knoweldge of preshared key that are being used. Using certificates will take care of the concern.
What would be the best route to go?
- cisco router as CISCO IOS CA Server
- changing current DMVPN to use certificates
- go with GET VPN
- go with Microsoft CA server
I am pretty sure someone over there uses certificates for Enterprise VPN authentication .
