Worse, the problem is being made worse at an alarming rate. MPLS VPN's are quicky replacing frame relay, ATM, and leased line circuits adding MPLS lables and VPN/VRF routes to edge routers. Various RIR's are pushing "PI for all" in IPv6 based on addressing availbility. Some networks are actually finally using multicast for IPTV services, generating much larger number of entries than the global multicast table would otherwise indicate.
It's not the RIR's fault. IPv6 wasn't designed with any kind of workable site multihoming. The only goal seems to have been to limit /32's to an "ISP" but screw you if you aren't one. There was no alternative and it's been how long now? PI, multihoming, multicast, etc. is reality because the internet is now Very Serious Business for many, many people. Yes, I know there's hacks like SHIM6 and I don't wish to go OT into a debate about them, so I'll just say that if there had been a viable alternative to multihoming as we know it I think it would have been given a go before policy got pushed to the RIR's to allow IPv6 PI. ~Seth
