Hierarchy Level


Defer initial multipath calculation until all BGP routes are received. When multipath is enabled, BGP inserts the route into the multipath queue each time a new route is added or whenever an existing route changes. When multiple paths are received through BGP add-path feature, BGP might calculate one multipath route multiple times. This slows down the BGP RIB (also known as the routing table) learning rate. With this feature enabled the router does not start BGP multipath calculation until end-of-RIB marker is received. Configure this option to delay multipath calculation.

Alternatively to delay the multipath calculation the BGP multipath job priority can be modified using multipath-build-priority configuration statement at [edit protocols bgp] hierarchy level.



Specify a value in seconds to indicate the maximum time that a device must delay the multipath calculation after a peer is up.

  • Range: 1 through 3600 seconds
