bgpRmAfiSafiInstallBestNPaths

The number of paths to install into the AFM for each
destination for a route of this <AFI, SAFI>.  This is used
to determine how many protecting paths are installed for
BGP-PIC Edge.
              
For the default value of 1, only the best path is
installed for each destination.
              
A value of N greater than 1 installs a best path and N-1
backup paths (if available) for each destination.  This
provides fast recovery from traffic loss after N-1
failures.  This is calculated using the same algorithm as
the 'best n' candidate additional paths.
              
If this value exceeds bgpRmAfiSafiAddPathBestN, then this
value dictates the number of additional paths to calculate
and install, but only bgpRmAfiSafiAddPathBestN will be
used as candidate additional paths for advertisement.
              
If ECMP best paths are available for a destination, next
hops will be installed into the AFM as follows.
-  ECMP next hops will be installed first according to
   bgpRmAfiSafiMaxIBgpEcmpRoutes,
   bgpRmAfiSafiMaxEBgpEcmpRoutes,
   bgpRmEntMaxIBgpEcmpRoutes and
   bgpRmEntMaxEBgpEcmpRoutes.
-  If bgpRmAfiSafiInstallBestNPaths is greater than the
   number of ECMP paths installed, then secondary next
   hops will be installed (if available) to take the total
   number of installed next hops up to the value of
   bgpRmAfiSafiInstallBestNPaths.
              
For example, if the maximum number of ECMP routes is 4,
and bgpRmAfiSafiInstallBestNPaths is 2, then routes will
be programmed as follows.
-  If ECMP next hops are available for a destination,
   these are installed into the AFM up to a maximum of 4.
-  If there is only one primary next hop to a destination,
   a secondary next hop is installed into the AFM if one
   is available.
              
Changing this field when the Admin Status is up will cause
all current Loc-RIB routes for this <AFI, SAFI> to be
recalculated.
