Hi
Understand from below article that we need to create an static arp record to make NLB work in multicast mode:
http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_example09186a0080a07203.shtml
However if the routing is done in FWSM, it seems able to complete the arp request so the static arp record is not necessary, also the routing is done in hardware even though "the incoming packets have a unicast destination IP address and multicast destination MAC", may someone confirm on that?
Thanks and Regards,
Leo
