Re: [uknof] ipv6 bgp filter size?
Hi Mike, Thanks for the reply sir, appreciated. From looking at the ipv6 route summary, filtering smaller than a /48 frees up a few hundred routes which isn't as many as I'd hoped. Would I cause problems for myself if I filtered on smaller than /32 for now, while I work on getting more memory sorted/new cam-profile/new router ?

In ipv4 bgp we filter out networks smaller than /24's but I'm not sure what people generally do for ipv6.

At present this kit is accepting everything down to /128 which is making me wonder if that is a bit wrong/too much as ipv6 grows. Would appreciate thoughts from others who run ipv6 bgp.

Re: [uknof] ipv6 bgp filter size?
Hi Johnny, If you filter on /32, you would be unable to reach any of the PI assignments (including my own) which are done on a /48 boundary. Thanks, Daniel.

There are lots of services only hosted in /48s - i.e. IPv6 PI, including many of the IPv6 root nameservers. You can probably look at RIR lists for which blocks they allocate which sizes of address from; actually what I suggest is you take default routes from your transits (as well as full routes) which will cover you (sub-optimally) until you can get the problem fixed. -- Will Hargrave LONAP Ltd +44 20 3137 8330
Re: [uknof] ipv6 bgp filter size?
Hello, Thanks Daniel and Will, I appreciate your advice. Still learning about V6 so your help is gratefully received. Think I'll have to filter on /32's and accept a default route for now while sorting out alternative's. Thanks once again everyone who has replied, have a great Friday :) Cheers, Johnny
[uknof] Offsite storage
Hi all, Can anyone offer us some offsite storage that we can dump to via SSH/rsync? Preferably across LONAP. Thanks. Gavin
Re: [uknof] Offsite storage
How much storage you after? How fast do you want access to it, 1G, 10G etc? Cheers, James.

Re: [uknof] ipv6 bgp filter size?
John, I need to ask. Why the requirement to do such drastic filtering? The v6 table size is pretty small. Plus you stated, after adjusting your own configuration, the /48 filter (the accepted common practice in v6-land) reduces cruft and provides a pretty clean table. Does the slightly less than 20,000 total routes (see http://bgp.he.net/report/prefixes#_prefixes plus other sites) cause you issues? Memory issues? Philosophical issues? Convergence issues? I'd strongly vote against you installing /32 filters for a few reasons. 1) The result won't be a complete (or valid, if you multi-home) routing table. 2) The implication of even one ISP doing this has ripples back to the RIR ISP allocation world. 3) These kinds of filters NEVER get removed. 4) Default route doesn't really fix things. 2000::/3 route even more-so! 5) Memory is cheap. Or am I still missing something? Martin Martin J.
