From Verio's customer pages, you can not only find instruction on how
Hi, If i understand your lines correctly, i think Verio's community policy meets your requirements. the customer should tag their routes via community to signal Verio of different routes, but also find that what Verio gonna send to their customers (i suppose it will do to their peers.) See Verio site for more detail: http://info.us.bb.verio.net/routing.html What's more, just a following of your comminuty-and-control problem. Do you think it a little dangerous - that let your downstream/peer that control your egress traffic via this community&local_pref intereaction ? I believe an NSP would prefer to control both inbound and outbound traffic, or at least otbound traffic. That maybe the reason that the community policy is not a widely practice. reagrds, Yu Ning -------------------------------------- (Mr.) Yu Ning ChinaNet Backbone Operation Networking Dep.,Datacom Bureau China Telecom.,Beijing(100088),P.R.C +86-10-66418121/66418122 -------------------------------------- ----- Original Message ----- From: Greene, Dylan <DGreene@NaviSite.com> To: <nanog@merit.edu> Sent: Tuesday, April 04, 2000 1:59 AM Subject: Community advertisement
Hello there,
All of the backbone NSPs I've spoken with (UUNET, Sprint, etc..) have offered to provide me with either full tables or partial (customer) routes.
What would actually be interesting to me would be full tables w/ that customer list tagged as a separate community. It isn't difficult to config, does anyone know if this is actually offered by any providers? If not, why not? It would be very helpful to know which routes stay on a single backbone, and which traverse peering links, etc.. The partial tables provide this, but there are situations where one wants to route other traffic to that provider, so a full table is necessary (default won't really work if you've got advertisements from other providers you _don't_ want to send that traffic to.)
I'd be interested to hear if others are doing anything similar to this, have requested it, etc. The standard community offering I've seen from anyone are the MED like 'set local_pref on our backbone' tags which helps direct inbound traffic, but there is little available for outbound.
Thanks, ..Dylan
