This lab also demonstrates another router, R1, to be the IPv4 route-reflector for it's BGP peers. R1 is the route-reflector for R2 through R6. R1 is also eBGP peered with BB3 and is receiving routes. This portion demonstrates how ipv4 bgp routes are unaffected by VPNv4 BGP routes and vice versa.
This one would be good to go back to, to keep VPNv4 and IPv4 BGP straight.
