Question

Options

• AInteroperability of MPLS VPN networks across two different carriers

• CIn an MPLS VPN network composed of multiple ASs, VPN routes need to be transmitted.
• DVPN routes are transmitted only via static routes, without the need for BGP VPNv4.
• EIn a Layer 2 VPN (VPLS) scenario, there is no need for Layer 3 VPN routing.

• A
