Hi Shraddha,

We noticed that RFC 5817 sets the TE Metric to 0xffffffff for graceful TE shutdown and the OSPF Link Overload draft uses MAX-TE-METRIC (0xfffffffe). Two Questions:

   1. MAX-TE-METRIC is being defined in the OSPF Link Overload draft – correct? It is not a reference from some other RFC or draft?
   2. Why not just use 0xffffffff like RFC 5817?

Thanks,
Acee
