# IP/MPLS & LDP label reallocation test

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