Global Crossing IPv6 on hold?
by Jeff Wheelhouse 15 Dec '09

15 Dec '09

Hi All, We recently received our ::/32 allocation from ARIN, and when we went to set up IPv6 BGP with one of our transit providers, Global Crossing, we were told new IPv6 sessions were (direct quote) "not available at this time." Attempts to get an ETA or even an explanation why have so far been fruitless. Can that be right? I've always thought of Global Crossing as an IPv6 leader. Has anyone else heard anything about this? Thanks, Jeff

level3 europe problems
by Bogdan 14 Dec '09

14 Dec '09

hello from friday, after a peer reset from level3, we've started to have some issues with the bgp session with level3 1. first they sent us just around 4000 prefixes (instead of ~300k) 2. then nothing, we opened a trouble ticket and they said they rebooted a router, and so on. (we saw an interesting graph in decix http://www.decix.net/content/network.html ) 3. after that, the connection seemed to be ok. all prefixes received but: - some websites, including level3.net were loading very slow sometimes, sometimes not at all. - dns issues with hosts around the world - some ipsec tunnel around the world not working, some did, and same with telnet/snmp. - mtr not working to some hosts, ping always looked ok. 4. the second i shutd the neighbor, all communication was ok. i made several tests, and as soon as the peer was up, the problem begun. peer down - all was ok on the other providers. did anyone else exeprienced this kind of issues? the ticket is still open, but we did't recieved any rfo etr for 2,5 days :)

Forget content, they're just along for the ride. When most service providers have eye-wateringly shite CGNs acting as intermediaries between eyeballs and content, the content providers will be motivated to move to v6 even if only as a means of damage control. > And > not even by node count, but by percentage of traffic.

Ah, that's something we don't have.

A proven technology, successfully implemented on millions of residential firewalls "isn't really a firewall, but rather "a disaster waiting to happen". Make you wonder what disaster and when exactly it's going to happen? Simon Perreault wrote: > We have thus come to the conclusion that there shouldn't be a > NAT-like firewall in IPv6 home routers. And that, in a nutshell, is why IPv6 is not going to become widely feasible any time soon. Whether or not there should be NAT in IPv6 is a purely rhetorical argument. The markets have spoken, and they demand NAT. Is there a natophobe in the house who thinks there shouldn't be stateful inspection in IPv6? If not then could you explain what overhead NAT requires that stateful inspection hasn't already taken care of? Far from the issue some try to make it out to be, NAT is really just a component of stateful inspection. If you're going to implement statefulness there is no technical downside to implementing NAT as well. No downside, plenty of upsides, no brainer... Roger Marquis
