Question

What happens here? config vpn ipsec phase1-interface edit Hub set net-device disable set tunnel-search nexthop end

a) Disables network device for VPN
b) Enables network device for VPN
c) Initiates VPN tunnel search
d) Modifies the VPN tunnel endpoint

Answer 1

The provided configuration lines are for setting up a VPN interface named 'Hub'. The 'set net-device disable' command stops the creation of a virtual network device, while 'set tunnel-search nexthop' configures the VPN to initiate tunnel searches based on the route's next-hop.

Step-by-step explanation:

The configuration commands in question are used for setting up a VPN (Virtual Private Network) in a device using a specific type of software that manages network security. The purpose of the configuration lines is to modify the behavior of the VPN connection.

Here's a breakdown of what each line accomplishes:

• edit Hub: This command selects the VPN interface named 'Hub' for editing.
• set net-device disable: This command disables the automatic creation of a virtual network device for the VPN interface (it does not disable an existing network device).
• set tunnel-search nexthop: It initiates a tunnel search based on the route's next-hop rather than the destination IP. This is useful in dynamic routing environments.
• end: This command ends the configuration session and returns to the main command prompt.
