A Virtual Private Network (or VPN) helps extend a private network over a public network privately, as the name suggests, and securely.It does this by creating a tunnel or private line from a local network to an external network (and vice versa) for the secure transmission of data. Jun 02, 2020 · Complementing Jorge A. Valentin Davila's answer. In a layer 2 VPN, L2 frames (usually Ethernet) are transported between locations. In the more general case, it's similar to a cable connecting two switches in separate buildings. In addition, the EVPN address family can also transport L2 to L3 address mappings, allowing sites to synchronise L2 to L3 mapping (ARP), cutting down on ARP broadcast. DCI – You can use L2 VPN (AToM for two sites, VPLS for two or more sites) or EVPN to achieve DCI as you need to interconnect the sites at L2.

One of the major differences between L2 and L3 VPN is the mechanism utilized to signal and set up the overlay network. L3VPN (RFC2547bis) would be extending the BGP protocol so as to allow PE’s for signaling which routes are available within which VPN’s.
Dec 14, 2018 · With a Policy-Based VPN, you need to specify manually on both sides of the VPN which subnets will be exposed from site A to site B and from site B to site A. On a standard Cisco router/firewall, you have to create an access-list (ACL) and specify in the ACL the subnets you are going to learn and advertise to the other side.
