About 30.0 / 24 prefix, C allocates a label 23 , the mapping is transmitted to the B ; B local to 30.0 / 24 allocates a label 22 , the mapping is transmitted to the A . An IBGP adjacency is established between R1 and R4 . The IBGP adjacency is established on the physical interface. Established between R1 and R5 , R4 and R6 basic concept Mpls traffic-eng tunnels ip rsvp bandwidth Network 10.1.34.4 0.0.0.0 area 0 Collect IP routing information obtained through other routing protocols Test and see the forwarding path of the data. So if you want to load balance based on messages ?

For R1 and R2 , they do not know the existence of the tunnel . When they go to 7.7.7.7/32 , only the IGP 's own routing is performed. Calculation, then R2 is likely to take the path of R4-R6-R7 ,ccna recertification, but we may prefer that these traffic can be transmitted through the tunnel , then for this requirement, autoroute can not be achieved, need to use Forwarding ajacency .
