routing dump / routing registry checks
by Curtis Villamizar 20 May '97

20 May '97

There is a new report at: http://figaro.ans.net/route-dumps/970520/overlap-summary.html Summary: There are 114 AS in which aggregates are registered and unregistered more specific prefixes announced but for which the aggregate is not announced. Some of these may be cases where the aggregate is not being formed due to a configuration error. There are 197 of these registered but unannounced aggregates. These aggregates overlapped 840 prefixes. There is an updated report on unregistered prefixes at: http://figaro.ans.net/route-dumps/970520/ These two reports used the May 9 routing dumps but use copies of the routing registries from May 19, reflecting changes made since May 9. The original reports are at: http://figaro.ans.net/route-dumps/ The main page has not been updated to reflect this third iteration. Curtis btw- This was previously announced to NANOG only. I'm not sure what distribution list is appropriate. Suggestions by private response please to avoid clogging the mailing lists.

Emergency backup for a small net
by Bradley Dunn 20 May '97

20 May '97

Hi, We have a small ISP customer that wants to run a circuit to another local ISP and the ISPs would use that pipe only in the case of primary link failure. The two ISPs would split the cost, etc. The obvious solution would be for both ISPs to set up BGP peering with their upstreams and not announce anything in normal operation. The upstreams would continue to statically route the smaller ISPs' blocks and the smaller ISPs would default to their upstreams. The smaller ISPs would also put in a default pointing at each other with a higher cost. Then in the case of primary link failure the ISP who still has a path to the net would begin announcing the other ISP's block(s) to their upstream. The upstream would in turn see this as a valid announcement and propagate it to the world. Therefore specificity should draw all the traffic to the correct place. The problem is both ISPs are small and have /24s from their providers. The /24s would be filtered by many, leading to only partial connectivity in the case of failure. (Partial connectivity is better than no connectivity, I guess...) Another possible solution I thought of is to use NAT. The small ISPs would use RFC1918 internally and use a block from their provider to translate into. When the primary link fails they switch over to using a block from the other ISP's provider. They would also have to use very low TTLs for their DNS zones and be prepared to switch the DNS zones to point to the other block. Does the NIC consider this efficient utilization to have a block lying around that only gets used when a link fails? An important thing to remember here is that the backup link will not be used in normal operation. This is not multihoming. They do not want load balancing. I would be interested to hear others' thoughts on this. If you reply privately I will summarize any interesting replies to the list. Thanks! pbd -- You can make it illegal, but you can't make it unpopular.

Update on Feb 1997 notes
by sob＠academ.com 20 May '97

20 May '97

The Gigaswitch notes are now on-line. As some of you know, there was a scheduling snafu with my return flight from San Francisco and I was unable to stay for Paul Vixie's second talk or the closing comments from Bill Norton. If someone else has notes from either of these they are willing to share, please send them along to me and I will put them up on the notes page for the Feb 1997 meeting. Thanks in advance and my sincere apologies for Paul and Bill for not being able to take notes from their presentations. I have already taken steps to insure that I don't have this problem for the June meeting. For those of you in the US, have a good Memorial Day Holiday. -- Stan | Academ Consulting Services |internet: sob(a)academ.com Olan | For more info on academ, see this |uucp: {mcsun|amdahl}!academ!sob Barber | URL- http://www.academ.com/academ |Opinions expressed are only mine.

RE: Root Nameserver Changes

But does the fact that these packets cross continents imply less redundancy ? Given the number of transatlantic cables in place and the new ones on the way, I do not think it is reasonable to assume that (in this instance) that all of Europe will disappear at once ? > To add European root name servers to the > list that North American operators use does > not do them a service. Well, we Europeans have *suffered* because of the lack (all one of) non-North American root name servers. "You" did not seem so worried then (note the quotes around the word "you"). Distributing name servers is an operational issue, and given enough transit services to them, this is not really a redundancy problem, mearly political.

18 May '97

Finally, I have been able to get all the notes (except those concerning the Gigaswitch) on line. I have also been able to get a number of slides on-line, but I don't have all of them. I expect to get the Gigaswitch notes on line later this week. -- Stan | Academ Consulting Services |internet: sob(a)academ.com Olan | For more info on academ, see this |uucp: {mcsun|amdahl}!academ!sob Barber | URL- http://www.academ.com/academ |Opinions expressed are only mine.
