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? <Shraddha>Yes. This value is introduced in this draft. The reason was that some implementation treat te-metric 0xffffffff as invalid value and do not setup paths through them. Using 0xffffffff-1 seemed like a safe option 2. Why not just use 0xffffffff like RFC 5817? <Shraddha>We can if we have the Working Group Consensus. Thanks, Acee
