I assumed a binary radix trie (not tree) because that's the normal cannonical version used by computer science students. Yes, as you outlined, there are many games you can play, if you're willing to make space/time tradeoffs. Regardless of the details, the point remains: if your data structures are largely constant, then you are more efficient searching a small data set vs. searching a large one. Tony

This decouples the policy table for the active forwarding table - providing more flexibility - at the cost of memory. You can set it to one of two mode - white list (if exist pass) or black list (if exist drop). The white list is what SPs have been interested in since you can fill the VRF with the prefixes from a peering partner/customer - then insure all source addressing coming from that customer matches the BGP prefixes being sent.

Wow - I'm going to need to dust off the tutorial materials on how uRPF and using the FIB as a policy enforcement tool works. Does uRPF need to scan through the entire FIB? Saying this is saying routers look through the entire FIB table to find the next hop? What ever happened to TRIE techniques? uRPF's look up is at the same speed as the forwarding look up. In fact, in many implementations, the "forwarding lookup" gets the source and destination address values from the FIB. Now, are there other ways of doing BCP38 - yes lots: - ACLs - Radius loaded ACLs - uRPF Strict-Feasible-VRF modes - IP Source Verify - DHCP Lease Query - NAT on the home CPE Why hasn't Cisco done uRPF Feasible path? Cause until recently, our CEF structures would not allow for feasible/alternate paths. If the FIB is your policy table, then _what_ you are limited to the capabilities of that FIB when using it to police the packet. Cisco has that now, so "feasible path" is just a matter of time to work through the coding queues. What I'm shaking my head over with this whole dialog is the 1990's thinking. BCP38 is out of date. Anyone who works, mitigates, analysis, and studies attack vectors on network systems know that checking the IP source address is one of many "Anti-Spoof" checks you need to do on the packet. With Ethernet and Cable, you need to do a MAC check. With all mediums you need to check the Prec/DSCP value (porn at Prec 6 does wonders for the routing protocols when there is congestion in the path). Then there is TTL values, Fragments, and other values which need to be policed on the edge. This is why uRPF - while helpful - is not the primary BCP38 tool people should be considering on the edge.

Randy, I don't think I implied anything of the sort. I did, however, pipe up when a BCP is mentioned that I endorse, and co-authored -- and likewise, cannot figure out for life of me, why there is such push-back from the Ops community on doing The Right Thing. Having said that, botnets don't need to spoof addresses -- the sheer dispersion of geographic and AS infection base renders the whole point of spoofing almost moot. And having said that, it doesn't make BCP 38 any less valid. - ferg -- Randy Bush <randy(a)psg.com> wrote: > I don't want to detract from the heat of this discussion, as > important as it is, but it (the discussion) illustrates a point > that RIPE has recognized -- and is actively perusing -- yet, ISPs > on this continent seem consistently to ignore: The consistent > implementation of BCP 38. oh? you have knowledge that this botnet attack used spoofed source addresses? randy -- "Fergie", a.k.a.

Fortunately, modern ACL implementations frequently use TCAMs (1 read) or tree based structures (log2(handful) + 1) as well. As always, the details of a particular implementation are everything. YMMV.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 We ran into similar attacks (couple days back) coming from non-spoofed address range (being initiated from valid prefixes). In working (w/ a co-worker of mine) on a network attack situation (trace process) for a 30,000 user location (serving 60 other school districts) running BCP38 & rate-limit which got ddos'd w/ about 8mpps. It appears that these attacks were coming from the inside which not only saturated devices along its way but also got amplified into several other networks also causing significant flaps to its peered connection (OC-xx). Besides being distracted with this incredible among of traffic flow our goal number one goal was to prevent this bleeding, thanks to the distributed monitoring sensors (maybe we got lucky) we were able to identify and sink-hole (null route) certain blocks (vlans) while we worked with the network/desktop team to isolate the infected machines. This was certainly a hair-pulling experience. The point that I'm trying to make here is, you can have data coming from a herd of comprised hosts (bots, self-propagating worms, spam-relays,fake http get request, backdoors, etc) that can attack against a well-protected system(s) so any kind of defense mechanism can/will get defeated. Then again, it doesn't mean one wouldn't want to follow well practiced prevention methods. Just curious, any ddos vendors want to share their success stories :-) regards, /virendra - -------- Original Message -------- Subject: Re: DNS DDoS [was: register.com down sev0?] Date: Thu, 26 Oct 2006 17:32:56 +0000 From: jerry(a)jdixon.com Reply-To: jerry(a)jdixon.com To: Robert Boyle <robert(a)tellurian.com>, owner-nanog(a)merit.edu, Patrick W.
