How do you disable IGMP-snooping on virtual nic macvtap?
Background: We have noticed that Juniper vSRX 15.1X49-D60 (Running on Ubuntu 16.04LTS Server KVM) is constantly reforming the neighbor relationships (~ ever 40 seconds) when connected to *any physical router (Juniper or Cisco).
We have narrowed this down to fact that 'igmp-snooping' needs to be disabled on the virtual nic "macvtap."
Our temporary work-around for this is to set the virtual interfaces to 'promiscuous' mode, however this is not preferable.
To diagnose this issue, we have three instances of virtual SRX running on Ubuntu 16.04 KVM with a p2p connection to a physical Cisco SRX240 and Cisco 3750G (configured for routing).
Attached is a log-adjacency from the Cisco router and a pcap from the virtual srx.
Thank you all in advance,
