Which of the following about inter-AS model C VPRNs is FALSE?

Within each AS, the ASBR advertises the system addresses of remote PE routers as labeled IPv4 routes.

PE routers in different ASs exchange VPRN routing information directly over MP-eBGP.

Within each AS, MP-iBGP sessions are established to exchange VPN-IPv4 prefixes between the PE routers.

ASBRs exchange the system addresses of PE routers as VPN-IPv4 routes over MP-eBGP.
