Hi all When we get newip, we should let the upstream know to expor it as there should have rule in their side. how about upstream provider, does they need to let their all bgp interconnect to know those our newip? If no, Can I know how it works? If they don't have rules each other, ls it any problems?
It depends on your upstream ISPs. Conventionally, some choose to place exact filters in place on BGP announcements that exactly match IP space that is registered with a RIR or LIR, some build those filters from IRR sources, and others just filter on the number of prefixes your sending (to avoid sending a whole table out on accident). I'm sure there are some other filtering schemes in place around the world. In the case of exact filters, you'll need to contact your upstream ISPs and ask them to update their filters. In the case of IRR-sourced filtering information, update the prefixes that you originate with your IRR provider. And in the case of max-prefix filtering, ask your ISP what they have their equipment set to. Cheers, jof
