An engineer is setting up a GRE tunnel between two routers. The tunnel source is configured as Loopback0 with IP 10.0.0.1, and the tunnel destination is 10.0.0.2 (the remote router's Loopback0). The engineer has configured the tunnel interface with IP 192.168.0.1/30. What additional configuration is required on the local router for the tunnel to be operational?

A route to reach 10.0.0.2 via a physical interface or routing protocol.

A route to reach 192.168.0.0/30 via the physical interface.

A NAT rule to translate the tunnel source IP to the physical interface IP.

A keepalive configuration to ensure the tunnel stays up.

After configuring a GRE tunnel, the engineer runs 'show interface tunnel 0' and sees that the tunnel is up/up, but the line protocol is down. What does this indicate?

The tunnel destination is unreachable, but the tunnel interface is still up.

The tunnel is configured with the wrong IP address on the tunnel interface.

The tunnel is not receiving keepalives from the remote end, so the line protocol is down.

The tunnel source interface is down, but the tunnel interface is still up.
