Usage Guidelines

Usage Scenario

In scenarios where servers are partitioned into multiple VMs, to allow flexible deployment and migration of VMs on multiple servers or devices, the common solution is to configure Layer 2 interconnection between multiple devices. However, this approach may lead to larger Layer 2 domains on the network and the risk of broadcast storms. To resolve this problem, the common method is to configure a VM gateway on an access device and enable proxy ARP anyway on the gateway so that the gateway sends its own MAC address to a source VM and communication between VMs is implemented through route forwarding. To enable proxy ARP anyway on an interface, run the arp proxy anyway enable command.

Example

# Enable proxy ARP anyway on GE 0/1/1

<HUAWEI> system-view
[~HUAWEI] interface GigabitEthernet 0/1/1
[~HUAWEI-GigabitEthernet0/1/1] arp-proxy anyway enable
