Answer: B,D

Explanation:

This VPN connects customer sites that use the same AS number. The as-override command is used in BGP configurations when connecting a customer site using BGP where both the service provider and the customer are using the same AS number. This command allows the service provider to replace occurrences of the customer’s AS number in the AS_PATH with its own AS number.

A Layer 3 VPN is configured. The configuration includes instance-type vrf, which indicates that it is a Layer 3 VRF (Virtual Routing and Forwarding) instance. This is typically used in MPLS Layer 3 VPNs to maintain separate routing tables for different customers.

A Layer 2 VPN would not typically use VRF instances or BGP for routing VPN traffic; instead, it would use protocols like LDP or BGP to signal the establishment of pseudowires for Layer 2 connectivity.
