Do we still lose packet with fast reroute? One of my students asked me this question. And I would like to share the answer with everyone.
MPLS Traffic Engineering
You need OSPF or IS-IS to distribute link information such as reserved, unreserved and used bandwidth, metric, link colouring information.These informations are used by CSPT ( Constraint based shortest path first ) algorithm.
Is MPLS mandatory for Traffic Engineering? What is Traffic Engineering in the first place ?
