Interoperation Of Vlt Nodes In A Pvlan With Arp Requests; Scenarios For Vlan Membership And Mac Synchronization With Vlt Nodes In Pvlan - Dell Z9500 Configuration Manual

Interoperation of VLT Nodes in a PVLAN with ARP
Requests
When an ARP request is received, and the following conditions are applicable, the IP stack performs certain operations.
• The VLAN on which the ARP request is received is a secondary VLAN (community or isolated VLAN).
• Layer 3 communication between secondary VLANs in a private VLAN is enabled by using the ip local-proxy-arp
command in INTERFACE VLAN configuration mode.
• The ARP request is not received on the ICL
Under such conditions, the IP stack performs the following operations:
• The ARP reply is sent with the MAC address of the primary VLAN.
• The ARP request packet originates on the primary VLAN for the intended destination IP address.
The ARP request received on ICLs are not proxied, even if they are received with a secondary VLAN tag. This behavior change
occurs because the node from which the ARP request was forwarded would have replied with its MAC address, and the current
node discards the ARP request.
Scenarios for VLAN Membership and MAC Synchronization
With VLT Nodes in PVLAN
The following table illustrates the association of the VLTi link and PVLANs, and the MAC synchronization of VLT nodes in a
PVLAN (for various modes of operations of the VLT peers):
