## What is OpenOverlayRouter?

OpenOverlayRouter (OOR) is an open-source implementation of the Locator/ID Separation Protocol (LISP, RFC6830). With OOR, hosts can change their network attachment point without losing connectivity, while maintaining the same IP address. OOR supports multiple interfaces (only one active at a time) and horizontal handovers across them. OOR requires that you configure an Endpoint IDentifier (EID), you may request one visiting https://github.com/OpenOverlayRouter/oor/wiki/Beta-network.

OOR main features are (version 1.0):

- Register to the Mapping System
- NAT-Traversal (as defined in draft-ermagan-lisp-nat-traversal-2)
- Support of multiple interfaces (only one active at the same time)
- Horizontal handovers
- IPv4 EIDs
- IPv4 RLOCs.

The OOR open-source code can be found at https://github.com/OpenOverlayRouter

If you are unsure of what OOR is we encourage you to visit our community website: http://www.openoverlayrouter.org/


Additionally, the first time that you run OOR you will be prompted to accept that it adds a VPN interface. This is used to encapsulate/decapsulate data packets.
