The $ : Learning-Phase (for Delayed Route Calculation) notation denotes that the BGP peer with this notation is learning bulk route updates. More than one peer can be in Learning-Phase. BGP BEST-Path selection is delayed until all the peers complete Learning-Phase. A peer can be in Learning-Phase only if BGP delayed route calculation feature is enabled and in specific scenarios described in the init-route-calc-delay command.

The # : RIB-IN phase notation denotes that a peer is learning bulk route updates. When one or more peer is in RIB-IN phase, BGP provides high preference for learning incoming route-updates and less preference for advertising routes (to outbound peers). An incoming route-update can possibly cause a BGP BEST-path change and eventually re-compute RIB-OUT for outbound peers. Slowing down RIB-OUT until all peers complete learning route updates will improve BGP performance. This feature is enabled by default and does not require additional configuration. Unlike BGP delayed route calculation, BGP BEST-Path selection is not delayed in this Phase.

This example displays summary information about dynamically created BGP neighbors.
