uBR7246 not using ARP Cache

Hi,

I admin a Cable Company ISP. WE have a uBR7246 Router that is not using it's arp cache. The router is sending about 4-6 arp requests a second to about 1600 Cable Modems causing the activity light on all cable modems to flash erratically. This is a waste of bandwidth. Can anyone help me with this problem? Thanks...

Re: uBR7246 not using ARP Cache

Try this suggestion ,since I was also expecting this.

Use the cable interface and conigure it with 'no arp arpa'. This can solve your problem.

Bye
