-1:
The left most 1 defines the route type, which in this case 1 means EVPN route type 1, also called Ethernet Autodiscovery route.
-10.200.0.7.0:
The above signifies the route distinguisher
-050000fc01000007d000:
The above signifies the unique 10 octect ESI value.
The type 1 ethernet autodiscovery route is used for multihoming scenario which provides the benefit of multipathing and mass withdrawal of routes. Remote leaf devices, can use multiple paths to send traffic because of this feature to the local leaf device. In cases where there is a local link failure or node failure, the remote leaf devices only have to withdraw a single A-D route associated to this leaf device instead of withdrawing routes associated with each and every mac-addresses (which could be 1000s of mac-address in virtualization use case), as such it provides faster convergence in cases of link and node failures. "This week datacenter up and running with EVPN VXLAN and the ADCX Juniper training course is a good place to learn about the bgp.evpn.0 route table, apart of standard junos docs.
