Hello,
we are in process of migration from 4 x EX4500 in VSS to 4x EX4600 in VSS,
on ex4500 we are using multicast arp record for microsoft nlb VIP and it is working perfectly for many years.
On ex4600 same cfg is not working, NLB IP (in this case 10.4.7.21) is not reachable (even from same vlan/gateway):
EX4500 cfg
set interfaces vlan unit 207 family inet address 10.4.7.1/24 arp 10.4.7.21 multicast-mac 03:bf:0a:04:07:15
set vlans Server-Mail vlan-id 207
set vlans Server-Mail l3-interface vlan.207
#show arp
03:bf:0a:04:07:15 10.4.7.21 email.local.local vlan.207 [vlan.207] permanent
root@ex4500# run show version
