interim SIDR meeting at NANOG 54
by Murphy, Sandra 27 Jan '12

27 Jan '12

The IETF SIDR wg plans an interim meeting, to be held in San Diego the Thu after the end of NANOG 54 (Thu Feb 9). The intent is to get operator input into two topics that have been energetically discussed on the sidr mailing list: replay-freshness protection and route leaks. The discussion of both topics has concentrated on operational impacts, so the opinions of operators would be useful. The announcement can be seen at: http://www.ietf.org/mail-archive/web/sidr/current/msg03881.html. I am working on logistic details with the NANOG hotel or others nearby. When details are final, I will post them to both this list as well as the IETF SIDR mailing list. --Sandy

ANNOUNCE: bgptables.merit.edu - understanding visibility of your prefix/AS
by Manish Karir 27 Jan '12

27 Jan '12

All, We would like to announce the availability of the bgpTables Project at Merit at: http://bgptables.merit.edu bgpTables allows users to easily navigate global routing table data collected via routviews.org. bgptables essentially processes the data collected at routeviews and makes is available in a somewhat easier to use interface. The goal of bgpTables is to represent global prefix and AS visibility information from the vantage point of the various bgp table views as seen at routeviews. The data is currently updated nightly (EST) but we hope to improve this over time. Please see the FAQ (http://bgptables.merit.edu/faq.php) for some simple examples of how you can use bgpTables. Some examples: - You can query for a specific ASN by entering the text 'as' followed by the AS number into the search box. For example to query for information about AS 237 you would enter 'as237' [without quotation marks] into the search box and then click 'search'. You can then use the view navigator map to switch to different routing table views for this ASN - You can query for a specific prefix by directly entering the prefix into the search box. For example to query for information about prefix 12.0.0.0/8 you would simply enter '12.0.0.0/8' [without quotation marks] into the search box and then click 'search'. You can then use the view navigator map to switch to different routing table views for the prefix. - You can find a particular prefix that you might be interested in by running a 'contained within' query via the search box. For example to quickly browse a list of prefixes contained within 1.0.0.0/8 to find the particular prefix you might be interested in, you can enter the text 'cw1.0.0.0/8' [without quotation marks] into the search box and click 'search'. You can then browse the resulting table to select the particular prefix you might be interested in. - You can simply enter the text 'as' followed by the company name into the search box then click search to view a list of possible matches for that text. For example, to view all matching google ASNs you can simply enter 'asgoogle' into the search box and click search. A list of possible matching ASNs that reference Google by name will be returned from which you an then select the particular ASN that is of interest to you. Comments, corrections, and suggestions are very welcome. Please send them to mkarir(a)merit.edu. Hopefully folks will find this useful. Thanks. -The Merit Network Research and Development Team

RE: XBOX 720: possible digital download mass service
by Thomas Cooper 27 Jan '12

27 Jan '12

Digital distribution like Steam have the infrastructure built for it. The entry fee for independent and smaller devs to Steam is way way lower than all the licensing crap that Microsoft offers with their XBLA, and for the larger companies, it costs next to nothing to host it digitally as opposed to the brick-and-mortar packaging (especially when the game requires Steam and you essential buy a CD key at the retail store, with added taxes, etc....) Besides, those console games are marked up to hell so I bet they make a pretty penny for brick-and-mortar sales. I doubt MS will try a full-blown Steam-like console digital distribution. -Thomas Cooper

Choice of address for IPv6 default gateway
by Daniel STICKNEY 27 Jan '12

27 Jan '12

I'm having trouble finding authoritative sources on the best common practice (if there even is one) for the choice of address for an IPv6 default gateway in a production server environment (not desktops). For example in IPv4 it is common to chose the first or last address in the subnet (.1 or .254 for example) as the VIP for VRRP/HSRP. I'm interested in input from production environments and or ARIN/RIPE/IANA/etc or top vendors. I've seen some documentation using <prefix>::1 with either a global prefix or link-local (fe80::1). Anyone use either of these in production and have negative or positive feedback? fe80::1 is seductive because it is short and the idea of having the same default gateway configured everywhere might be simple. At the same time using the same address all around the network seems to invite confusion or problems if two interfaces with the address ever ended up in the same broadcast domain. What about using RAs to install the default route on the servers? The 'priority' option (high/medium/low) easy fits with an architecture using an active/standby router setup where the active router is configured with the 'high' priority and the standby 'medium'. With the timeout values tuned for relatively rapid (~3 seconds) failover this might be feasible. Anyone use this in production? I note that VRRPv3 (and keepalived) and HSRP both support IPv6. Since we use VRRP for IPv4, using it for IPv6 would keep our architecture the same, which has merit too. Thanks in advance, Daniel STICKNEY
