Route Reflector Client Design Question
by Erik Sundberg 07 May '18

07 May '18

I have a RR Client design question...... CORE1-------------------2x10G-----------------------CORE2 | | | | | 10G Ring | | | | | PE1----------PE2----------PE3----------PE4----------PE5 -Core1 & Core2 are RR Reflectors with full IPV4 Tables (ASR9K) -MPLS LDP Enabled -IGP is ISIS -Each PE peers only with Core1 and Core2 as RR Clients with iBGP -PE's are only receiving a default route from the Core Routers due to TCAM size of 20K (ASR920's\ME3800's) -The ring does not have that much traffic on it <500m, so I do not want to use additional 10G ports on the Core's and is why I have it in a 10G U ring. -Primary link to the cores is via the PE1 --- CORE1 Like......... For this discussion the link between PE5 to CORE2 is set up as a backup link. The scenario is I have traffic between PE2 and PE3. Since the PE's are only receiving a default route from the Cores. Traffic is label switch from PE2 - PE1 - Core1 does a IP lookup at Ingress then label switches back to PE1-PE2-PE3. This ends up being 5 hops and doubling the traffic on the link to the Cores. My questions is how do I get traffic to go directly between the PE's without going to the Core Routers? 1. Can I enable iBGP between the PE's in a full mesh to allow traffic between the PE's without going to the core's. Or does this break the Route Reflector model? 2. Create a route policy on the Core's advertising routes learned from the PE's back to all the PE's on the ring. 3. Is this one of the down sides to U Rings? 4. Leave it alone and move on to bigger and better things....

Checking on best practice being followed with regards to enabling NSF or NSR or both on ASR 9k. Which option can be beneficial and considered to be a standard approach. Thanks!

RE: Route Reflector Client Design Question

You could optimize the packet hop count by making smaller but more rings. For example, make one ring with CORE1, CORE2, PE1, PE2, PE3. And another ring with CORE1, CORE2, PE4, PE5. If you configure "route-reflector-client" on the CORE, and mesh the clients, then you can additionally configure "bgp client-to-client reflection disable". However, if the CORE is just sending a default route, then you probably have default-originate and no RR clients on the CORE. Then you don't need to disable reflection, because it's not reflecting anyway. (reflection refers to the reflection of routes, not reflection of packets). You could send limited important or heavily used prefixes between the PEs using route policy without blowing up the TCAM.

Open Souce Network Operating Systems
by Colton Conor 04 May '18

04 May '18

If one were to deploy whitebox switches, X86 servers, low cost ARM and MIBPS CPE devices, and basically anything that can run linux today, what network operating system would you recommend? The goal would be to have a universal network operating system that runs across a variety of devices. >From low cost residential CPE's with wifi to switches to BGP speaking routers. Is there anything that can do it all today? I will use something like OpenWRT as an example. I don't consider this anywhere near carrier grade, but it runs on X86 and low cost routers. I don't think it will run on whitebox switches though. Mikrotik RouterOS would be another example as it can run on low cost Routerboards, and X86 servers. But it is not opensouce. Is there any up and coming projects to look into?

survey on BGP prefix hijacking
by Alberto Dainotti 02 May '18

02 May '18

Dear NANOG Community, BGP prefix hijacking remains a problem for Internet routing, despite the (partial) use of RPKI or detection services. We would like to hear your opinions on BGP prefix hijacking (concerns, existing defenses, needs, etc.) that would help us research new defense mechanisms both for its detection and mitigation. Please help us by answering this short (< 10min, 21 questions) and anonymous survey. Survey URL: http://tinyurl.com/hijack-survey *** The survey *** This survey is part of a joint research effort by CAIDA (www.caida.org) and the ICS-FORTH (www.ics.forth.gr) research institute, to study (a) operator awareness of BGP prefix hijacking attacks/incidents, (b) presently used defenses against BGP prefix hijacking, (c) the willingness to adopt new defense mechanisms, and (d) reasons that may hinder the deployment of BGP prefix hijacking defenses. We expect the findings of this survey to increase the understanding of existing BGP hijacking defenses and the needs of network operators, as well as help us design and implement new defense mechanisms that we will present to the operator and scientific communities. A summary of the aggregate results will be published as a part of an article/conference paper. Thank you in advance, and we look forward to your responses! Alberto (CAIDA) and Pavlos (ICS-FORTH)

"Weird" Traffic about 10 hours ago
by Mike Hammett 01 May '18

01 May '18

This is going to be extremely scientific. </sarcasm> Did anyone else see "weird" stuff going on about 10 hours ago, about 6 PM Central on April 30th? I'm based in the Chicago area and have a large client on the east coast. I saw about a 25% drop in traffic for a half hour to an hour. Another Midwestern ISP also saw about 25% drops on two different upstream connections. A friend of mine runs an ISP in Virginia. He reported a dip in traffic (though didn't report how much of a drop), but also pings and IPSEC\L2TP worked, but couldn't SSH or do other activities. That friend reported another ISP in Virginia had problems at that same time. An ISP in Cyprus reported issues at that time. I'm looking to firm up what kind of issues and verify the time. Yet other ISPs report no problems at all. Smooth ramps on traffic graphs as one would expect at the beginning of prime time. I thought maybe "something" happened in Ashburn (fiber cut, DWDM card failure, etc.) as my client has a wave from the east coast to me in Chicago, but then the Midwestern ISP shouldn't have any dependency on Ashburn, given Chicago and Dallas. Then there's the guy in Cyprus, which shouldn't have any bearing on anything that happens over here in the States. I thought maybe it was an epic failure at one of the CDNs or other content networks, but then that wouldn't impact SSH or other management activities. Anyone else have any other data to help figure out what caused this? ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com
