If I use a single Management server it works:
Question with the IP addresses assigned:
the initial VMs are running:
v-154-VM <public-IP-3> <Private-IP> <control-ip-169.x.x.x>
s-285-VM <public-IP-2> <Private-IP> <control-ip-169.x.x.y>
I do not see the Public IP anywhere, not even advertised on vni1000 or any
other, the public VNI is there was created by the system, but nothing is there
- No IP addresses advertised
I used VLAN/VNI vxlan://1000
vxlan1000: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9050 master brvx-1000 state
forwarding priority
There are 2 VNETS assigned
