Abstract
Disclosed are systems and methods for scaling Massively Scalable Data Center (MSDC) networks with a large number of end-point tunnels utilizing Equal-cost multi-path routing (ECMP). The systems and methods can use the NO-OP label operations to maintain single ECMP objects to switch a set of segment routing tunnels that share the same ECMP links. The forwarding engine can determine the use of the NO-OP label operation and update a received packet to enable the use of the single ECMP objects of the set of segment routing tunnels.
