'''XORP''' is an [[open-source software|open-source]] [[Internet Protocol]] [[routing]] software suite originally designed at the [[International Computer Science Institute]] in Berkeley, California. The name is derived from ''eXtensible Open Router Platform''. It supports OSPF, BGP, RIP, PIM, IGMP, OLSR.

The product is designed from principles of software modularity and extensibility and aims at exhibiting stability and providing feature requirements for production use while also supporting networking research.<ref>{{cite web

In July 2008, the [[International Computer Science Institute]] transferred the XORP technology to a new entity, XORP Inc., a commercial startup founded by the leaders of the opensource project team and backed by Onset Ventures and [[Highland Capital Partners]].<ref>{{cite web

}}</ref>  In February 2010, XORP Inc. was wound up, a victim of the recession.  However the open source project continued, with the servers based at [[University College London]].  In March 2011, Ben Greear became the project maintainer and the www.xorp.org server is now hosted by Candela Technologies.

The XORP codebase consists of around 670,000 lines of [[C++]] and is developed primarily on [[Linux]], but supported on [[FreeBSD]], [[OpenBSD]], [[DragonFlyBSD]], [[NetBSD]].  Support for XORP on [[Microsoft Windows]] was recently re-added to the development tree. XORP is available for download as a [[Live CD]] or as source code via the project's homepage.

The software suite was selected commercially as the routing platform for the [[Vyatta]] line of products in its early releases, but later has been replaced with [[Quagga (software)|quagga]].<ref>{{cite web

**{{IETF RFC|1657|link=no}} (Definitions of Managed Objects for the Fourth Version of the Border Gateway Protocol (BGP-4) using SMIv2)
*[[Open Shortest Path First]] version 2 (OSPFv2) and version 3 (OSPFv3):
**{{IETF RFC|2328|link=no}} (OSPF Version 2)
**{{IETF RFC|3101|link=no}} (The OSPF Not-So-Stubby Area (NSSA) Option)
**{{IETF RFC|5340|link=no}} (OSPF for IPv6)
*[[PIM Sparse Mode]] (PIM-SM):
**{{IETF RFC|4601|link=no}}
**{{IETF RFC|5059|link=no}}
* [[IGMP]] v1, v2, and v3:
**{{IETF RFC|2236|link=no}} (Internet Group Management Protocol, Version 2)
**{{IETF RFC|3376|link=no}} (Internet Group Management Protocol, Version 3)
*[[Multicast Listener Discovery]] (MLD v1 and v2):
**{{IETF RFC|2710|link=no}} (Multicast Listener Discovery (MLD) for IPv6)
**{{IETF RFC|3810|link=no}} (Multicast Listener Discovery Version 2 (MLDv2) for IPv6)
*[[Virtual Router Redundancy Protocol]] (VRRP v2):
**{{IETF RFC|3768|link=no}}

==User interface==
XORP provides a command line interface for interactive configuration and operation monitoring. The interface is implemented as a distinct application called ''xorpsh'', that may be invoked by multiple users simultaneously. It interacts via [[interprocess communication]] with the router core modules. The command line language is modelled after that of [[Juniper Networks]]'s [[JunOS]] platform.
