Configuring Dynamic Learning of ARP Entries with Multicast MAC Addresses
After a device is enabled to learn ARP entries with multicast MAC addresses, it can generate ARP entries for the received ARP packets with multicast MAC addresses as source MAC addresses.
Context
An IP address maps
to a multicast MAC address in some service scenarios. For example,
as shown in Figure 2-10, the Router connects
to the NLB cluster through the Layer 2 switch LSW. The NLB cluster
works in multicast mode and has a multicast MAC address as the cluster
MAC address. After the Router is enabled to learn ARP entries with multicast MAC addresses,
it can generate dynamic ARP entries. This reduces a network administrator's
workload and decreases network operation and maintenance costs.
