Question:
Consider the following MPLS network with four MPLS-enabled routers R1 to R4.
Suppose that R5 and R6 are now MPLS enabled. We want to perform traffic engineering so packets from R6 destined for A are switched to A via R6-R4-R3-R1 (connection 1), and packets from R5 destined for A are switched via R5-R4-R2-R1 (connection 2).
- Which router is the Ingress and which is the Egress for each connection?
- For each connection, which router(s) are considered Label Switch Routers and which are Label Edge Routers?
- If the label assignment method was downstream, which router will start to distribute labels for each connection?
- Using Downstream, unsolicited, and ordered label distribution, you are required to propose labels and to fill in the four tables in the above figures using the interfaces depicted in the figure for the two connections.
