Topology:
Use configuration from L2VPN task #3 as initial configuration for this task.
Requirements:
1. Reduce the number of LDP sessions in SP network to two (2).
2. Further reduce the overhead for tunneled traffic to 8 byte only.
Solution:
Highlight the text below to reveal the solution.
This task requires understanding for AToM Static Pseudowires.
Using static pseudowires removes the need for targeted LDP session between the tunnel endpoints, and also allows to disable the control word, which is required for Ethernet traffic tunneling.
Note that you need to configure the mpls label range for dynamic and static labels, before configuring the static pseudowires.
