Description (partial)

RIB table shows a BGP route with a backup path even though the said path is not present in BGP table.

1. RIB redistributes a path to BGP.
2. This redistributed path becomes the backup path in BGP (due to the "additional-paths install ..." configuration).
3. BGP downloads the backup path (which is the redistributed path from RIB) to RIB.
4. RIB deletes the redistributed path
