No, he is saying that the CPE1 and CPE2 are each using provider independent address space and are multihomed to ISP1/ISP2 and ISP3/ISP4 respectively. If the *private* addresss space of CPE1/CPE2 were visible to the ISPs, then it wouldn't really be a V*Private*N. Such things are common in MPLS, ATM, FrameRelay, and the newer L3VPN technologies that are sold as managed solutions. You need four IPsec SAs. They could be transport+GRE/IPIP tunnels rather than IPsec Tunnel model SAs with a routing protocol on-top though. -- Michael Richardson <mcr+IETF@sandelman.ca>, Sandelman Software Works -= IPv6 IoT consulting =-
