To provide Internet access for VPN-A using CE-1 as the hub CE, the Internet traffic from Site 2 will indeed follow the path: PE-2 -> PE-1 -> CE-1 -> PE-1 -> GW-1. This is because CE-1, acting as the hub, will route internet traffic through itself before reaching the internet gateway. Additionally, RIB groups are not necessary to leak routes between the inet.0 and VPN-A.inet.0 tables, as the routing between these tables can occur without special configurations.
