I recently took the reins after our net admin jumped ship. I'm awful green with Juniper gear and apologize for my questions ahead of time here. 🙂
I was allocated a new /22 from ARIN recently, and can't seem to get it to advertise. I've added the addresses to the main export policies for both my carriers. I've also run 'clear bgp neighbor soft x.x.x.x' and I've even tried without specifying the neighbor. When I check with 'show route advertising-protocol bgp x.x.x.x' I see my previous advertisements, but don't see any of the new ones.
