you can check http://tools.ietf.org/html/rfc6391 how this works, there are no constraints on the flow label value other than it must not be a reserved label value (0-15). The label value is only significant for the encapsulating/ingress PE, it just ensures to allocate and use the same label for all indivisible flows, to ensure those flows are sent via the same ECMP path. Section 3 of the RFC talks a bit about who the PE should allocate and assign labels. The egress PE just needs to know that there is a flow label present on the PW (statically or signalled via LDP), and it just pops it. hope this helps.. oli _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
