Re: Provider standard ARP Timeout?

I am using arp-timeout 900 (means 15min), because of having problems with
my upstream ethernet connection and everything is ok, and I have not seen
any relation between MAC Address aging time and that, aging time is default
300sec for me ;)
Thanks

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?
