ACE How can we do a static arp to multicast mac address?

Answered Question
Nov 27th, 2009

I have a architecture that uses ACE to do Firewall Load Balancing. I need to add a static map of a VIP IP to a multicast mac address (Microsoft servers with NLB in multicast mode). The ACE does not accept multicast mac address in the static arp statement, anybody knows why? Is there any other way to do that?

The ACE doesn't support multicast MAC addresses. This is a limitation impose by the hardware used on the boards. Syed has previously proposed a workaround at . I don't know if that will be applicable in your case.
