Which security feature can protect DMVPN tunnels?

Show Suggested Answer Hide Answer
Suggested Answer: D

In an MPLS PE router, CE advertised routes are segmented from other CE routers by assigning CE-facing interfaces to different Virtual Routing and Forwarding (VRF) instances12. A VRF is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time. By associating a network interface with a VRF, the network layer (Layer 3) has a different view of the network topology. This allows the segmentation of routing paths for traffic from different customers or different types of traffic.In the context of MPLS, VRFs are used to create separate routing instances for each customer on a PE router3.

I thought RADIUS could also play a role, but not for tunnels, right?

TACACS+ and RADIUS are more about authentication, right? I feel like they wouldn’t directly protect the tunnels themselves.

Ah, I remember now - IPsec is the standard way to secure DMVPN tunnels. The encryption and integrity checks it provides are crucial for protecting those dynamic tunnels. Definitely going with A on this one.

Hmm, I'm a bit unsure on this one. I know DMVPN is a VPN technology, but I can't remember if IPsec is the specific security feature used. I'll have to think this through carefully.

I'm pretty sure IPsec is the right answer here. DMVPN tunnels need strong encryption and authentication, and IPsec provides that.

TACACS+ and RADIUS are authentication protocols, not security features for the tunnels themselves. RTBH is for blackholing traffic, which doesn't seem relevant here. I'm leaning towards IPsec as the best answer.

If you use RADIUS to secure your DMVPN, does that make it a 'Dance-Mode VPN'?
