   @weizhouapache 
   
   Thank you for the response. My apologies for my late response.
   
   Currently the system running the management server and the first host is 
connected to the switch via two ethernet interfaces `A (10.4.1.1/16)` and `B 
(10.6.1.1/16)`. 
   **Note**: Both interface A and interface B is connected to an untagged port 
on the switch (we are using 802.1q VLAN on the switch and it only has options 
for tagged and untagged ports). 
   The ethernet interface A is used for creating `cloudbr0` and the ethernet 
interface B is being used to created `cloudbr1`.
   `cloudbr0` is being used by the Management Network which is using isolation 
of type VLAN
   `cloudbr1` is being used by the Guest and Public Network whose isolation 
type is what we are discussing about.
   
   Provided the scenario, correct me if I am wrong, based on my understanding 
if I used VLAN as my isolation type for the Public and Guest, I am assuming, I 
will need to connect `ethernet interface B` associated to `cloudbr1` to a trunk 
or tagged port on the switch. 
   I already tried isolation of type VLAN  for the Public and Guest Network and 
had the same issue where VM on the second host couldn't communicate virtual 
router on the first host. So I am assuming `interface B` being connected to an 
untagged port on the switch was the issue.
   
   However, if I use isolation type of VXLAN, which uses layer 3 UDP packets,  
`ethernet interface B` associated to `cloudbr1` can be connected  to an 
untagged to access port.  
   
   Correct me if I am wrong, provided, my assumptions are correct, I am 
assuming VXLAN is more likely to work with the existing switch configuration   
(`interface A` and `interface B` being connected to  untagged switch ports)
   
   Additionally, I am wondering, is there any additional configuration I have 
to do the system running the management server and the host or install any 
additional software on it. 
   As I did try isolation type of VXLAN for the Public and the Guest Network 
with VLAN isolation type for the Management Network. It seemed like, I was 
having internet connectivity issues on the VMs (regardless of the host they are 
on). I tried installing Ubuntu 20.04 server, however, the process for fetching 
updates from the server and downloading was very slow and would eventually 
crash. I am really confused as to why I was getting such behavior. I checked, 
the management server log, however, I didnt notice any error messages.
