Page 1207 highlights
• 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): Table 95.
