Guys,
I have a customer who is using 2 sun boxes running checkpoint firewall
connected with a hub to our router, then out to the internet. They are both
running as primary and are sharing a virtual ip and mac address. The
customer wants us to statically arp map 140 ips to mac addresses on the
router, which we are not willing to do as per upper management. I suggested
he try to implement it on his own box and arp them to us. He has informed
me that his firewall people told him that under normal conditions it would
work but since they are looking to arp map ips to multicast mac addresses it
would not work. Firewall guy says that cisco routers do this on purpose so
as to not to use the multicast mac addresses on the internet.
1. Is this true?
2. Is there any documentation on this? (Looked and did not find any)
