The index of the AALL IP prefix access list to use for route exports to the peer group for this AFI/SAFI. Route export policy applies any export IP prefix access list before any export route map, and the route must be permitted by both to be exported. The export route map can apply its own prefix lists in addition to any export IP prefix access list. Route export uses a single export IP prefix access list - see the description of the bgpPeerAfiSafiExportIpAallPre field for details. This field is used for dynamic and configured peers. For a description of how this field is used for the latter, see the description of bgpPeerTable.
