lots of prepends
by Mikael Abrahamsson 19 Feb '09

19 Feb '09

Today 85.119.176.0/21 was announced by AS20912 with 177 prepends. I noticed 20912 modulo 256 is 176. AS47868 modulo 256 is 252 which matches this mondays prepend-incident. So, what router OS will put 20912 into a byte and thus end up with 176 in something like "set as-path prepend last-as <no of prepends>" ? It needs to be fixed. Has anyone noticed any ill effects with IOS and using "bgp max-as"? Will it just drop any prefixes with long as-paths and no other ill operational effects? -- Mikael Abrahamsson email: swmike(a)swm.pp.se

Re: do I need to maintain with RADB?
by Zaid Ali 19 Feb '09

19 Feb '09

It's not entirely free since you have to pay an AS maintenance fee and if you are assigned a netblock directly then you pay maintenance on that also. I would rather maintain everything in one place rather than paying an extra $495 to RADB if my BGP peers can source it from ARIN.

Hi Guys. Do you ever see single fiber 10Gb/s X2 or Xenpak transceiver? (I know about SFP, but never see X2 or Xenpak before)

Network diagram software

I'd like to know what software people are using to document networks. Visio is obvious but feels like a straight jacket to me. I liked netviz but it seems owned by CA and unsupported nowadays. What do you use? /Tias

protect users from victimisation by the likes of this : http://www.bleepingcomputer.com/forums/topic204619.html For years (decades?) I've been DNS hijacking to criple worm ridden machines associating with my wifi nodes etc. That only deals with a few threats. I'd like to feel confident in using blackhole routes to combat maleware proliferation too. Any tools available to age out male-routes after a given period of time?

Re: IPv6 Confusion
by Ralph Droms 19 Feb '09

Independent of this conversation, there has been some parallel interest in this problem area in the IETF. There is enough interest to suggest writing a draft defining additional options for DHCPv6 to allow "DHCPv6-only" operation. I'm writing as chair of the dhc WG to ask you, the operators who are asking for these extensions to DHCPv6, to provide clear technical requirements. What problem are you trying to solve and how do you want to solve it? Reply directly to me - no need for further congestion on this mailing list - and we can discuss those requirements. The deadline for draft publication prior to the upcoming IETF meeting in SF is March 3, so please respond soon. Thanks in advance... - Ralph
