BGP+Label Vs MPLS LDP label

Hi all

i have a question that is related to INE Full Scale Lab 4, i have noticed that enabling the Inter-AS MPLS VPN will not work unless i make the LSP over the IGP not over BGP+Label, that is why i found your solution to redistribute the BGP into IGP only in this LAB.

is this a coincidence or do i am missing something here, when i try to shut the inter-AS link between R3 & R5 if found the ping failes between the 2 ASs VRF FOO sites (in case only using BGP+Label), but when converting to use the MPLS LDP label derived from IGP process i found every thing ok, although the MPLS forwarding table seems to be fine (static route over XR1 for the transport address has been added as well)

thanks for your support
