NTAC Peering Working Group

[David Farmer <>]

FYI, I just sent the following note the Internet2 NOC.  I think we need a set of ASNs that should not be accepted from other NRENs, This should include things like GGC nodes, DNS Root Server anycast nodes, AS112 nodes, global transit providers, etc...

There are several HE(AS6939) routes being leaked into the R&E route table.

Subject: RENU advertising GGC node
To: Internet2 NOC <>

RENU is advertising a GGC node via UBUNTU into the Internet2 R&E route table. Please stop accepting these routes from them. As these routes are in the R&E route table they were overriding at least one route (104.237.191.0/24) I learn from a GGC node in Minneapolis. I have dealt with this in my local route policy, but I suspect others may have an issue too.

Note AS36040 is the ASN Google uses for GGC nodes;

Thanks.
