1. Introduction
Route Flap Damping (RFD) [1] is a mechanism for BGP speaking routers
intended to improve the overall stability of the Internet routing
table and reduce the load on the CPUs of the core routers.
Unfortunately, due to the dynamics of the protocol, common simple
configurations can do more harm than good, see [3,4].
1.1 Background
In the early 1990s the accelerating growth in the number of prefixes
being announced to the Internet (often due to inadequate
prefix-aggregation), the denser meshing through multiple inter-provider
paths, and increased instabilities started to cause significant impact
on the performance and efficiency of the Internet backbone routers.
Every time a routing prefix became unreachable because of a single
line-flap, the withdrawal was advertised to the whole core Internet
and handled by every single router that carried the full Internet
routing table.
It was soon realized that the increasing routing churn created
significant processing load on routing engines, sometimes
sufficiently high load to cause router crashes.
To overcome this situation RFD was developed in 1993 and has since been
integrated into most router BGP software implementations. RFD is
described in detail in RFC 2439. RFD is now used in many service provider
networks in the Internet.
1.2 Coordination of flap damping parameters
When RFD was first implemented in commercial routers, vendor
implementations had different default values and different
characteristics. As inconsistency would result in different rates
of flap damping, and therefor introduce inconsistent path selection
and thus behavior that was very hard to diagnose, the ISP community
introduced a consistent set of recommendations for flap damping
parameters, so that ISPs deploying RFD would treat flapping
prefixes in the same way.
This call for consistency resulted in the RIPE Routing Working Group
producing first ripe-178, then ripe-210, and finally the ripe-229
documents [2], following consensus of the Routing Working Group.
The parameters documented in ripe-229 were considered, at time of
publication in 2001, the best current practice.
2. Current Status of Route Flap Damping
Research in the years following the introduction of RFD into BGP
implementations, and the publication of the RIPE Routing Working Group
recommendations, has demonstrated that there are real and signficant
problems with RFD as deployed on the Internet today.
2.1 Impeded Convergence
Perhaps the best known work highlighting major problems with RFD is that
by Zhuoquing Mao and colleagues, presented at Sigcomm in 2002. Following
presentations by Randy Bush and colleagues explain the research work more
accessibly.
The major issue is that if one path is withdrawn, all BGP speakers will
use best path selection to pick the next best path, and advertise this
best path to all their neighbours. These neighbours will see a change in
path; a change in path is a change in attribute, so the prefix as seen
on a neighbouring router will attract a flap penalty - even though
that path is perfectly valid and there has been no disappearance of
the prefix from the routing table [5].
And this path "hunting" goes on throughout the Internet - a simple
prefix withdrawal can result in the appearance of a major flap event a
few AS hops away in the Internet, with the result that vendor default
and even the RIPE-229 recommended flap damping parameters will mark the
prefix to be suppressed. While the operator can see this is an error,
the routers are simply reacting to the circumstances presented to
them.
2.2 Updates transiting the network
Problems are not just caused by path "hunting". Each implementation
of BGP either has differing values of the Minimum Route Advertisement
Interval (MRAI) Timer (the amount of time a router waits before passing
on a route update) or does not implement MRAI at all in favour of
the vendor's own throttling algorithm.
Some implementations pass on the update without waiting at all, others
wait for 30 seconds, etc. These differences mean that update messages
transiting different ASNs using different vendor equipment will arrive
at the target router at different times. This router will see these
different messages, and will consider each one for best path options.
This will more than likely result in a different best path offered to
its neighbours for each message update arriving.
The result of this is that a simple update message from one ASN would
be seen as a multiple route flap event a few ASN hops away - when in
fact there was no instability whatsoever. There have been actual
measurements where this resulted in a single prefix withdrawal
producing 41 BGP events a few hops away!
Not only is the MRAI timer a potential source of problems, but also
differences in CPU loadings and CPU speed will result in different
update times for prefixes announcements passing from router to router.
These differences will also contribute to the effects described above.
3. Solutions
Possible solutions to the problems summarised above have been proposed and
analysed in the work by Zhouqing Mao and colleagues.
However, despite publication in 2002, there has since then been no
desire expressed from the ISP industry for these modifications to be made
to the BGP implementations. Nor has there been any activity by the BGP
implementors to enhance their flap damping implementations to follow
those recommendations.
As the power of routers has increased, the original needs for BGP Flap
Damping is no longer a major concern for operators or router equipment
vendors as it was in the mid-1990s when route flapping consumed a
signficant percentage of the CPU of early routers. In fact, the
negative effects of RFD, as described above, have become the major
concern, the cure has become worse than the disease!
4. Recommendation
This Routing Working Group document proposes that with the current
implementations of BGP flap damping, the application of flap damping
in ISP networks is NOT recommended. The recommendations given in ripe-229
and previous documents [2] are considered obsolete henceforth.
If flap damping is implemented, the ISP operating that network will
cause side-effects to their customers and the Internet users of their
customers' content and services as described in the previous sections.
These side-effects would quite likely be worse than the impact caused
by simply not running flap damping at all.
5. Conclusion
With current vendor implementations, BGP flap damping is harmful to
the reachability of prefixes across the Internet. We would like to
encourage more work to correct some of the issues highlighted by the
work of Mao et al [3], to allow the viewing of prefix flap statistics
without applying flap damping, and permit more flexible per eBGP
neighbour damping configuration features for network operators.
