Simulate feature - BGP Peer and Route Path Changes  

Could you help simulate the staging of new BGP peers, route-maps, and new routes to understand how they might impact route path behavior?  

I am planning to stage a change that involves adding a new link and BGP peer, with the expectation that routes will prefer the new path after the change. Can this scenario be simulated in the forward network to validate the expected behavior?  

So far, I’ve attempted to simulate the changes, and I can see the new/modified interfaces and the transit IPs. However, I don’t see the BGP peer.  

Am I missing something in the simulation process? Any guidance would be appreciated.  

Are there any limitation with the simulation feature.
