We also buy Level3 here in Minneapolis and Milwaukee markets. Good products good support... Can be a bit high priced at times... We buy through the wholesale group (Chicago) and get better pricing. Let us know if we can help...

Doug, We buy Level3 but will probably phase them out due to cost that is significantly higher than the marketplace. From a technical perspective, they have been an outstanding provider.

Re: Number of prefixes received exceeds limit - HE IPv6 routes via the route servers?

I found the other missing piece in our configuration and Rob was right about filters. We've got an explicit deny against ^6939_ from the route server because of our bilateral peering with HE and that's keeping our IPv6 routes from the route server down to 45 and 49 routes respectively so setting a limit of 150 is within reason. But the routes you sent wouldn't have matched the filter, hence the prefix limit was exceeded. Everyone else must have a 13K+ limit and therefor didn't notice the additional paths being injected. Or folks haven't put a prefix-limit on their IPv6 neighbors because if this was a full table, that's nearly 23K routes... -James > We're upgrading to ASRs soon, and they have a check for empty prefix > lists. > > On 8/20/15 15:12 , James Stahr wrote: >> Is someone just start re-advertising HE via the route server or did we >> just configure today a session for HE to the route server?

Re: Number of prefixes received exceeds limit - HE IPv6 routes via the route servers?

by David Farmer

Sorry guys that was us, or one of our participants. They made some changes about an hour ago, and announced the whole IPv6 table to us. We had a prefix list configured, but it seems to be empty now, not sure how or when that happened. We're upgrading to ASRs soon, and they have a check for empty prefix lists.

This is not correct. We only advertise our customer routes to the route servers. We currently send 11764 routes, and have not made any recent changes. -- Rob Mosher Senior Network and Software Engineer Hurricane Electric / AS6939 On 8/20/2015 4:18 PM, Doug McIntyre wrote: > On Thu, Aug 20, 2015 at 03:12:10PM -0500, James Stahr wrote: >> Is someone just start re-advertising HE via the route server or did we just >> configure today a session for HE to the route server?

Number of prefixes received exceeds limit - HE IPv6 routes via the route servers?

by James Stahr

Is someone just start re-advertising HE via the route server or did we just configure today a session for HE to the route server? It was my impression that they only did bilateral peering.
