I regularly used to lower the ARP timeout to 5 minutes (to match the mac-address-table aging limit) on devices running on ATM LAN-E segments and saw no ill effects. -saxon On 10 August 2012 08:23, Jay Nakamura <zeusdadog@gmail.com> wrote:
Cisco default ARP timeout is 4 hours. Do anyone change that to something shorter in a provider environment for customer with Ethernet connectivity? What is a good value to set it to?
Are there any impacts for lowering the timeout? Other than higher CPU util for doing ARP a lot more on the router?
