Which of the following is TRUE concerning unnumbered VPN Tunnel Interfaces (VTIs)?
A.
They are supported on the GAiA Operating System.
B.
Local IP addresses are not configured, remote IP addresses are configured.
C.
VTIs can only be physical, not loopback.
D.
VTIs cannot be assigned a proxy interface.
A
Unnumbered VTI
For unnumbered VTIs, you define a proxy interface for each Security Gateway. Each Security Gateway uses the proxy interface IP address as the source for outbound traffic. Unnumbered interfaces let you assign and manage one IP address for each interface. Proxy interfaces can be physical or loopback interfaces.
Unnumbered interfaces are supported for Gaia and IPSO (3.4 and higher) platforms.
Configuring Unnumbered VTIs
Working with unnumbered interfaces eliminates the need to assign two IP addresses per interface (the local IP, and the remote IP Address), and the need to synchronize this information among the peers.
If the VPN Tunnel Interface is unnumbered, local and remote IP addresses are not configured. This interface is associated with a proxy interface from which the virtual interface inherits an IP address. Traffic initiated by the Security Gateway and routed through the virtual interface will have the physical interface’s IP Address as the source IP.
