https://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k-r6-2/lxvpn/configuration/guide/b-l2vpn-cg-asr9000-62x/b-l2vpn-cg-asr9000-E VPN (Ethernet VPN) and L2 VPN (Layer 2 VPN) are both technologies used for providing Layer 2 VPN services over an IP/MPLS network. E VPN is a more recent technology that provides a number of advantages over L2 VPN, including support for multi-homing, fast convergence, and efficient use of network resources.
When configuring E VPN native on a router, there are several parameters that must be matched between the E VPN and L2 VPN configuration modes. The correct answer to this question is option D: EVI (Ethernet VPN Instance).
An EVI is a unique identifier that is used to identify a specific E VPN instance within the network. It is similar to a VFI (Virtual Forwarding Instance) in L2 VPN. In order for E VPN native to work properly, the EVI must be configured with the same value in both the E VPN and L2 VPN configuration modes.
Option A, interface, is not correct because the same interface can be used for multiple EVIs. Option B, address family, is not correct because E VPN and L2 VPN can use different address families. Option C, bridge domain, is not correct because E VPN and L2 VPN can use different bridge domains.
In summary, when configuring E VPN native in a router, the EVI must match in both the E VPN and L2 VPN configuration modes.
