If you use Equal Cost Multipath (ECMP) in a Shortest Path Bridging (SPB) scenario, the Intermediate System-to-Intermediate System (IS-IS) protocol sends multiple routes with the same destination to the routing manager. IS-IS can add up to eight equal cost routes with the same destination to the routing table and the router uses one route for traffic forwarding based on load management. Use the ECMP Pathlist feature to control how many equal-cost paths to add to the routing manager for the same destination.
Note
Different hardware platforms can support a different number of ECMP paths. For more information about the maximum number of ECMP paths supported on the switch, see the scaling information in VSP 8600 Release Notes.
For information about how to configure ECMP Pathlist, see Configure ECMP and Configure ECMP.
