Re: IPv6 Route Server sessions down at FL-IX
by Randy Epstein 23 Oct '25

23 Oct '25

Greetings Members, For now, we’ve mitigated the situation by dropping sessions with the member we were hearing the malformed attribute from and notified their NOC. We are also going to plan an emergency maintenance to upgrade our version of BIRD (and its dependencies) in the near future that should filter this malformed attribute from being advertised to other members. To reiterate, this is only affecting members with Juniper routers as far as we can tell. There’s a perfect storm that enables this to happen, unfortunately. The IPv6 route server sessions are stable at this time. If you see any further issues, please let us know.

This is similar to the issue we experienced last week but on v4 sessions. This is not affecting members at CIX-NoVA as we are running a newer version of BIRD which blocks this attribute. We will arrange to upgrade our route server software (and related dependencies) as soon as possible. In the meantime, we are trying to track down the source of the malformed attribute so we can filter and contact the member’s NOC. Once we have an update, we will let you know.

Re: Some v6 Peering Sessions down with FL-IX and CIX-ATL route servers

FL-IX / CIX-ATL Members, Just a quick update that the route with the malformed attribute has been filtered about 40 minutes ago and sessions appear stable again. We are looking into this further to see how this can be mitigated in the future and will have updates once we have a solution available.

What we are receiving from the member routers on these downed sessions is “Received: Malformed attribute list”. A common thread appears to be that all the downed sessions are from Juniper routers. We’re still verifying this, but that seems to be the pattern thus far. Once I have some more information, I will update the mailing list.

If you are currently colocated within CoreSite, and your port is being transported to another location, we can now terminate you locally. Please get in touch with us and we’re work with you on provisioning a new port to migrate you.
