16-10 IP Configuration
Syntax
ip proxy-arp
no ip proxy-arp
Parameters
None.
Defaults
Disabled.
Mode
Interfaceconfiguration:C2(su)‐>router(Config‐if(Vlan1))#
Usage
ThisvariationoftheARPprotocolallowstheroutertosendanARPresponseonbehalfofanend
nodetotherequestinghost.ProxyARPcanbeusedtoresolveroutingissuesonendstationsthat
areunabletorouteinthesubnettedenvironment.TheSecureStackC2willanswertoARP
requests
onbehalfoftargetedendstationsonneighboringnetworks.Itisdisabledbydefault.
Example
ThisexampleshowshowtoenableproxyARPonVLAN1:
C2(su)->router(Config)#interface vlan 1
C2(su)->router(Config-if(Vlan 1))#ip proxy-arp
