Soft Reconfiguration
Router normally stores prefixes which have been received from peer after policy application
- Enabling soft reconfiguration means router also stores prefixes/attributes prior to any policy application
New policies can be activated without tearing down and restarting the peering session
Configured on a per-neighbour basis
Uses more memory to keep prefixes whose attributes have been changed or have not been accepted
Also advantageous when operator requires to know which prefixes have been sent to a router prior to the application of any inbound policy
