The index of the Route Map this configuration uses for route imports. The default value of 0 means no route map is defined, and all routes will be imported. If the peer is a member of a peer group then DC-BGP chooses whether to use the peer or peer group's import policy based on the flags in bgpPeerConfigUsage2. This field isn't used if the import route map is configured at the peer AFI/SAFI or peer group AFI/SAFI level - see the description of the bgpPeerAfiSafiImportMap field for details.
