multipath load balance" to distribute traffic load between two paths (1 ebgp and 1 ibgp) paths on router PE1 and PE2
N ! \

N ibgp --P---

My FIB shows two labeled paths installed one for ebgp and one for ibgp. and my LFIB shows only the ebgp route.
So in case PE1 receives a IP packet destined for CE1 network, it distributes the load between ebgp link and ibgp link. sending ip packet to CE1 and labeled packet to PE2. Since PE2 recevies a labeled packed it checks its LFIB finds a only a ebgp route and routes the packet to CE2.
The question here is
is this the property of LFIB, not to install ibgp routes even though they are present in the FIB, or is this an exceptional case. Can someone direct me to a link where in depth explaination is given about this topic
