[c-nsp] Microsoft NLB vs Cisco

[Tim Durack]

Anyone using Microsoft NLB Multicast mode for a cluster?

It requires a static arp entry on Cisco, as the cluster ip resolves to
a multicast mac, which can't/shouldn't be learned via arp.

So we do something like: "arp a.b.c.d 0100.5e7f.xxyy arpa"
Apparently this results in software switching the adjacency on a
Sup720, which is painful to say the least.

Any suggestions?
