Observations about the possible addition of a session between a router reflector and its client were documented in Request for Comments (RFC) 6774, which discusses the distribution of diverse Border Gateway Protocol (BGP) paths. Specifically, RFC 6774 observed that BGP as it is typically deployed has no mechanism for distributing paths that are not considered the best path between speakers. However, the possible addition of a session between a route reflector and its client could enable a BGP router to distribute alternate paths.

RFC 6774 does not document possible modifications to the bestpath algorithm, nor does it document possible software upgrades for provider edge (PE) routers that are acting as route reflector clients. Although the document does discuss a possible means of distributing paths other than the best path, the means by which BGP determines the best path to a destination were not changed. Therefore, no software upgrade is required.

The BGP AddPaths proposal, not RFC 6774, proposed the possible addition of a fouroctet Path Identifier to Network Layer Reachability Information (NLRI) in order to enable BGP to distribute multiple paths.
