Per RFC2547bis the use of Route Reflectors is supported in the service provider core. Multiple sets of route reflectors can be used for different types of BGP routes, including VPN-IPv4, etc. The 7210 SAS-K 2F6C4T or 7210 SAS-K 3SFP+ 8C can only be configured a route reflector client. It cannot be used as a route reflector ‟server” in the network.
