ip local-proxy-arp
Enable/disable Layer 3 communication between secondary VLANs in a private VLAN.
Syntax
[no] ip local-proxy-arp
To disable Layer 3 communication between secondary VLANs in a private VLAN, use the no ip local-
proxy-arp command in INTERFACE VLAN mode for the primary VLAN.
To disable Layer 3 communication in a particular secondary VLAN, use the no ip local-proxy-arp
command in INTERFACE VLAN mode for the selected secondary VLAN.
NOTE: Even after you disable ip-local-proxy-arp (use no ip-local-proxy-arp) in a
secondary VLAN, Layer 3 communication may happen between some secondary VLAN hosts, until the
address resolution protocol (ARP) timeout happens on those secondary VLAN hosts.
Defaults Layer 3 communication is disabled between secondary VLANs in a private VLAN.
