28 # IP/MPLS & LDP label reallocation test
29 # Create 4 routers connected like this: R1--R2--R3--R4--
30 # The goal is to push packets from R1 to the R4 shmif1 (the right one) interface
31 # Enable MPLS forwarding on R2
32 # Disable IP forwarding and enable MPLS forwarding on R3
33 # Start ldpd and wait for adjancencies to come up
34 # Add an alias on shmif1 on R4 for which we already have a route on R3
35 # Now: * R4 should install label IMPLNULL for that prefix
36 # * R3 should realloc the target label from IMPLNULL to something else
