This field is deprecated. It is retained for back compatibility. Use the bgpPeergrAfiSafiImportIpAallPre field instead. The index of the IP prefix list to use for route imports from the peer group for this AFI/SAFI. Route import policy applies any import IP prefix list before any import route map, and the route must be permitted by both to be imported. The import route map can apply its own prefix lists in addition to any import IP prefix list. Route import uses a single import IP prefix list - see the description of the bgpPeerAfiSafiImportIpPre field for details.
