NLB 叢集電腦會透過 ARP 回應 NLB 叢集 MAC 位址 (Multicast MAC address),switch 便會將封包送至 NLB 叢集的 switch ports [註:有些 switch 無法處理 Multicast MAC address] 如何區分 Unicast MAC address 與 Multicast MAC address? 首先我們先看看 MAC address 的結構,共有 32bits 如下,在 IP Multicast...
MAC地址有单播、组播、⼴播之分。单播地址(unicast address)表⽰单⼀设备、节点,多播地址或者组播地址(multicast address、group address)表⽰⼀组设备、节点,⼴播地址(broadcast address)是组播的特例,表⽰所有地址,⽤全F表⽰:FF-FF-FF-FF-FF-FF。当然,三层的IP地址也有单播、组播、⼴播之...
MAC地址分成两部分,前24位是组织唯一标识符(OUI, Organizationally unique identifier),后24位由厂商自行分配。 MAC地址有单播、组播、广播之分。单播地址(unicast address)表示单一设备、节点,多播地址或者组播地址(multicast address、group address)表示一组设备、节点,广播地址(broadcast address)是组播的特例,表示所有...
(unicast MAC),还有组播MAC地址 (multicast MAC)。接口收到组播包,会把此包的目的MAC地址 (是个组播MAC)和自己的MAC地址比较,如果组播地址相同,就会接受此包。这样,局网内这个组群的所有成员,都会收到送往该组群的组播包
address are 0x01005e, the 25th bit is 0, and the 23 least significant bits are the same as the 23 least significant bits of an IPv4 multicast address, as shown in the figure. For example, the multicast MAC address corresponding to the IP multicast address 224.0.1.1 is 01-00-5e-00-01...
This is my first time setting up Windows NLB. I would like to verify one thing about the multicast\unicast mac addresses. I realized a unique mac address is created for the NLB cluster. My question is as soon as the cluster is created, will this new cluster mac address be available righ...
A first node may transmit, to a second node, based on a unicast MAC address of the second node or a multicast MAC address associated with the second node, a discover message that may include a first MAC address or a first range of MAC addresses. The first node may receive an offer ...
Unicast vs. multicast Both types of communication, unicast and multicast, have clear similarities, particularly when you compare them with broadcast. The broadcast has its own address. All users on the network recognize it and can therefore respond to the data packet. Unicast and multicast on ...
When you use the multicast method, each cluster host retains the original MAC address of the adapter. In addition to the original MAC address of the adapter, the adapter is assigned a multicast MAC address, which is shared by all cluster hosts. The incoming client requests are sent to all ...
By default, the device discards and does not respond to received NS request packets that match the local device and have a unicast destination MAC address and a multicast destination IP address. To enable the device to respond to such packets, run the set unicast-mac multicast-ip ns reply en...
