HA setup for 3820 with virtual-macs
I'm trying to work out how best to setup virtual macs in an HA enviroment and the documentation isn't so clear. I've got an HA setup now that works fine except in a failover where there is a slight bit of down time due to MAC caching for the virtual IPs assigned for the two main SIP routing interfaces (M10 and M00). So, it looks like to solve that issue we need to assign a virtual mac that matches for both devices. Assuming we have the "base" mac addresses of:
00:08:25:xx:x5:f0
00:08:25:xx:x1:40
then, based on the documentation, the mac addresses for use in a virtual-mac scenario would be:
