ARP Request on shared vlan in vCMP-guest

Hi experts! My plan was to install a second vCMP-guest on my BIG-IP 5200v-box. But for some reson only one of the vCMP-guest recives the ARP broadcast request and not the other when i use the same shared VLAN, in this case DMZ6.

 

tcpdump -ni DMZ6 -e -p arp - shows that only one of the guest recives the arp-requests.

 

Egress arp-request works as excpected, from both guests. Same version software - 13.1.0.1 b0.0.8 .

 

Any ideas are appreciated! Thanks /Otto
