Or to keep the question short: Best way/practices to add a downstream eBGP session (to transit a prefix/traffic to a customer) so that it doesn't clash with my existing network on the same router(s). Thanks. śr., 20 mar 2024 o 00:10 LU napisał(a): > Hi. > > So, the Linux BGP routers perform pac

Re: Adding a downstream ebgp connection. How to keep it separate?

Hi. So, the Linux BGP routers perform packet forwarding. Up until this point they were handling only my own network/prefixes/traffic. Everything is using the default linux/bird main tables. I want to provide connectivity to the customer. I would announce his prefix to a select few of my upstream

Hi, I think you need to start with explaining why do you want to keep customer and upstream routes in separate tables. Regards, Alexander On Tue, Mar 19, 2024 at 1:39 PM LU wrote: > > Hello. > > I have two BGP routers with bird 2.4. Each router maintains some eBGP > connections to upstreams wh

Adding a downstream ebgp connection. How to keep it separate?

Hello. I have two BGP routers with bird 2.4. Each router maintains some eBGP connections to upstreams where I announce my prefixes. These routers have an iBGP connection between themselves to exchange routes learned from those eBGP connections. I do some filtering on the eBGP connections (like se
