Hello, We are currently working with simulating a PE router in MPLS architecture. We run zebra and ldp with below configuration and facing issues in swapping and popping of label in zebra. In my MPLS table I have the following entries, zebra_2# show mpls table Inbound Outbound Label Type Nexthop Label -------- ------- --------------- -------- 16 LDP 192.168.100.2 3 17 Static 192.168.100.2 18 But still zebra is not swapping the label and also not forwarding the received traffic (inbound label 16/17) to the respective nexthop. Is there any special command to activate mpls configuration ? Can someone help us in a configuring zebra MPLS to pop label and swap label? Thanks, Vijayalakshmi
