Usage
Information
This command enables soft-reconfiguration for the BGP neighbor specified. BGP
stores all the updates the neighbor receives but does not reset the peer-session.
You cannot set this configuration for a peer that is associated with a peer group.
Similarly, you cannot associate a peer to a peer group if that peer is already
configured with these settings.
CAUTION: Inbound update storage is a memory-intensive operation. The
entire BGP update database from the neighbor is stored in memory
regardless of the inbound policy results applied on the neighbor.
NOTE: This command is supported in BGP Router Configuration mode for
IPv4 Unicast address only.
