Each customer VRF imports 200, and exports its address block with RT 100.
In this way, the ISP VRF sees ...

Device D and Device E are considered to be nonclients because they have explicitly configured peer relationships with each other. To make them RRroute reflector clients, remove the neighbor 192.168.5.5 statement from the configuration on Device D, and remove the neighbor 192.168.0.1 statement from the configuration on ...

The BGP Additional Paths feature requires the user to take three
general steps:
Specify whether the device can send, receive, or send and receive additional paths. This is done at the address family level or the
neighbor level, and is ...
