I have revisited this.
So VRRP on a vm on ESX.
I stopped using VRRP, i didn't want to turn on promisc mode for my vswitches and I didn't want to create a seperate port group.....
But I have found that VRRP is going to be handy again, so I went looking, also went looking to see how I can do tagging to the VM as well.
So I found this article http://vmnomad.blogspot.com.au/2011/07/ ... an-id.html
and http://kb.vmware.com/selfservice/micros ... Id=1003806
where it talks about Virtual Guest Tagging (VGT), which gets around the need to have promisc mode !!!!
so I need to test this, as I haven't used a tag interface in routeros, but I presume it works the same as the other ones so .... this is looking real good.
My only concern now is 1 interface for all the vlans
as I am using a E1000 and routeros has no native nic driver I am concerned about performance ...
Done some more reading and thinking about it and I think I will not use vlan 4095 as I have too much traffic to be mirrored to but a new port group for RouterOs with promis mode allowed sounds like the way to go
