I have failed to understand the process of assigning labels. Take for example, a route, say 192.168.41.0 is generated by router A which is configured as an Edge-LSR. This router advertises this network to its up-stream neighbors B and C. Router C receives a new FEC and assigns it a Label (Independent control) without sending a request to Rtr A. I thought that when router A receives a new FEC, it automatically pushes a label to this route and then advertises it to the upstream neighbors. Why then is there that possibility of Rtr C being able to assign a Label to a route received from an Edge-LSR?
Thanks,
