Static MAC address entry and MS NLB - IPv6

I have seen other discussions regarding Static MAC address entries on IPv4, but what of IPv6?

We have MS NLB solutions and they are working fine.

We have Cisco 6509/6504, Version 12.2(33)SXI5


But then we have a new one for a new ActiveDirectory solution, and on those networks we have implemented IPv6.


To put it short: How is Static MAC address entries and MS NLB solved in IPv6 (i.e arp ip.ip.ip.ip mac.mac.mac ARPA gi1/1). I can't seem to find much examples or documentation on this? Is it replaced with another function?


The reason I ask is twofold.

1. I really want to know :-)

2. The NLB cluster seem to drop IPv6 traffic at even intervals, witch seems to correspond with NLB transition.




Thanks in advance

Hi, Did you try adding the following command to your switch: ipv6 neighbor ipv6_address (vlan where cluster is) mac_address This seems to work for me. I also needed to add the MAC address/port map of the clusters to the MAC address table.
