This section describes how to deploy proxy ARP anyway when the gateways to which VMs are connected have the same IP address.
In scenarios where servers are partitioned into VMs, to allow flexible deployment and migration of VMs on multiple servers or switches, the common solution is to configure Layer 2 interconnection between multiple switches. 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 switch 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.
Before configuring proxy ARP anyway, complete the following tasks:
Connect interfaces and set their physical parameters to ensure that the physical status of the interfaces is Up.
Configure link layer protocol parameters for the interfaces to ensure that the link layer protocol status of the interfaces is Up.
