摘要： According to an example, a method for forwarding multicast data packets includes receiving a first multicast data packet having a first multicast address, in which the first multicast address belongs to a first multicast group having a multicast source inside of a data center and sending the first multicast data packet through a designated router (DR) router port and a gateway router port, in which the DR router port and the gateway router port correspond to a virtual local area network identifier (VLAN ID) identified in the first multicast data packet.

摘要： A gateway RB may search for an ARP entry of the destination IP address of an IP packet. The gateway RB may generate an Ethernet header based on a VLAN identification and a MAC address in the found ARP entry and a first local MAC address. The gateway RB may generate an Ethernet packet by adding the generated Ethernet header to the IP packet, and send out the Ethernet packet via an egress port in the found ARP entry; wherein the founded ARP entry is generated by the gateway RB based on a received TRILL-encapsulated ARP packet and a VSI on the gateway RB associating with the first local MAC address and the destination IP address of the IP packet belong to the same VLAN.
摘要翻译：网关RB可以搜索IP分组的目的地IP地址的ARP表项。网关RB可以根据找到的ARP表项中的VLAN标识和MAC地址生成以太网报头，并生成第一本地MAC地址。网关RB可以通过将生成的以太网报头添加到IP分组来生成以太网分组，并通过发现的ARP表项中的出口端口发送以太网分组; 其中创建的ARP表项由网关RB基于收到的TRILL封装的ARP报文和与第一本地MAC地址相关联的网关RB和该IP报文的目的IP地址属于同一个VLAN的VSI生成。

摘要： An edge switch receives a VM classification policy and an executing policy corresponding to each VM class distributed by a policy controller. The executing policy comprises information of each service node for processing a message and an executing sequence of the each service node. The edge switch receives a message sent by a VM connected to the edge switch, determines a VM class corresponding to the message according to the VM classification policy and determines an executing policy corresponding to the VM class. The edge switch encapsulates the message according to information of each service node to be executed by a VM of the VM class and an executing sequence, and sends the message, so that the message is sequentially sent to the each service node to be executed by the VM of the VM class to execute a service policy.

摘要： A first access switch in the first Fabric receives a notification sent by a second access switch in the first Fabric, and the notification includes a nickname of the second access switch. The first access switch identifies an egress interface to a TRILL path from the first access switch to an access switch corresponding to the nickname in the notification. The first access switch stores the egress interface to the TRILL path in a fiber channel (FC) forwarding table. The first access switch forwards a received FCoE packet by using the egress interface stored in the FC forwarding table. The FCoE packet is forwarded by the first access switch without encapsulation with a TRILL header.

摘要： ECMPs are selected from multiple TRILL paths to a gateway. The source MAC address of a received Ethernet packet whose destination MAC address is the MAC address of the gateway is replaced with a local MAC address. A path is selected from the ECMPs, and the Ethernet packet whose source MAC address has been replaced is sent via the selected path.
