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.
