Need help with Time Warner announcing my new /24 on their network
Hello we are an independent ISP single homed with bandwidth from Time Warner Cable fiber. I was wondering if a TW tech could reach out to me. We've received an allocation from ARIN that I've asked TW to announce on our behalf, we issued the LOA, and first line says that it is setup but we are not seeing the block in any looking glasses. Since we are not multi homed nor have our own AS TW did a static route from their gateway router /IP to our router but they are saying we need to do a next hop statement and to point the new /24 back to their gateway ip? We have gone over this a few times and I am not clear on this and how it would affect them announcing our /24 to Radb etc. I was under the impression that once the route was announced it would show up in Radb even without us doing anything on our end yet.

router bgp YOURAS# neighbor TWIP next-hop-self This tell your router to advertise your IP addresses with your router's address as the next hop. BGP does not do this automatically because in more complicated configurations it's often not the desired result.

From what he has written, he is not doing BGP with his upstream. In this case what is he supposed to be doing next hop self on?
Sounds like TW have messed something up, and are not redistributing your prefix. Regards, Dave
Besides, swapping next hop is default in eBGP sessions. Next-hop-self is only needed for iBGP. On 8 October 2015 at 18:16, Dave Bell <me@geordish.org> wrote:
