Hi, all. Perhaps I'm missing something but I've got a question about mpls. Should there be some previous agreement between lsr about label numbers to be mapped and flooded? If so, where the specs talk about this? Have a look to the following scenario; let's suppose we are using unsolicited ordered control: a ------ x ------ y ------- b 1.- x and y are mpls lsr. 2.- x is egress for a then it maps label 1 to fec a, install it for forwarding and advertise this map to y. 3.- y is egress for b then it maps label 1 to fec b, install it for forwarding and advertise this map to x. 4.- x tries to install mapping 1-b received from y. 5.- y tries to install mapping 1-a received from x. 6.- Then both lsr could have the same label "1" mapped to two different fecs: a and b. Is this possible? Is there something I haven't understand yet?
