RFC 7196 Making Route Flap Damping
نویسنده
چکیده
Route Flap Damping (RFD) was first proposed to reduce BGP churn in routers. Unfortunately, RFD was found to severely penalize sites for being well connected because topological richness amplifies the number of update messages exchanged. Many operators have turned RFD off. Based on experimental measurement, this document recommends adjusting a few RFD algorithmic constants and limits in order to reduce the high risks with RFD. The result is damping a non-trivial amount of long-term churn without penalizing well-behaved prefixes’ normal convergence process.

BGP Route Flap Damping Algorithms
Route flap damping (RFD) plays an important role in maintaining the stability of the Internet routing system. It functions by suppressing routes that persistently flap. Several existing algorithms address the issue of identifying and penalizing route flaps. In this paper, we compare three such algorithms: original RFD, selective RFD, and RFD+. We implement these algorithms in ns-2 and evaluate ...
متن کاملBGP Dynamics during Route Flap Damping
The BGP routing protocol uses a mechanism called Route Flap Damping [13] to limit the impact of connectivity instability to any individual sites. Although it is believed that this damping mechanism contributes to the stability of global Internet routing, the exact effects of damping has not been thoroughly examined in a large scale network setting. Previous work [8] has shown that damping can b...
متن کاملRoute Flapping Effects on OSPF
Route flap is an undesirable phenomenon in the Internet and needs to be eliminated for more stable and robust networks. In this paper we present our observations of such persistent route flaps on OSPF in some detail. We show how flaps adversely affect OSPF routing and communication environment in general through our experiments. The current OSPF’s implicit timer damping function is found ineffi...
متن کاملStabilizing BGP, Safely
Route instability is widely recognized as a major problem in the Internet. Core routers are barraged with millions of updates daily, leading to massive infrastructural costs and worsened data-plane performance. Route flap damping provides some protection against instability, but introduces pathologies and reduces availability. With concerns about the scalability of the routing system prompting ...
متن کاملRoute Flap Damping Made Usable
The Border Gateway Protocol (BGP), the de facto inter-domain routing protocol of the Internet, is known to be noisy. The protocol has two main mechanisms to ameliorate this, MinRouteAdvertisementInterval (MRAI), and Route Flap Damping (RFD). MRAI deals with very short bursts on the order of a few to 30 seconds. RFD deals with longer bursts, minutes to hours. Unfortunately, RFD was found to seve...
