Inclusive Multicast Ethernet Tag route type specific EVPN NLRI 由以下内容组成:

               +---------------------------------------+
               |  RD (8 octets)                        |
               +---------------------------------------+
               |  Ethernet Tag ID (4 octets)           |
               +---------------------------------------+
               |  IP Address Length (1 octet)          |
               +---------------------------------------+
               |  Originating Router's IP Address      |

有关此路由的过程和用法, 请参阅第 11 节 ("Handling of Multi-destination Traffic"), 第 12 节 ("Processing of Unknown Unicast Packets") 和第 16 节 ("Multicast and Broadcast"). IP 地址长度以 bit 为单位. 为了进行 BGP route key 处理, 只有 Ethernet Tag ID, IP Address Length 和 Originating Router's IP Address 字段被视为 NLRI 中前缀的一部分.
