vlan question

[Ted Laurent]

I have a cluster that I've created a vlan on its nodes.   I've verified from the cli I can ping other cluster nodes on the vlan.   I can't figure out how to add the network pointing to those in the manager.   

Any ideas? 

Here is what the netplan looks like...

tlaurent@h2:~$ cd /etc/netplan
tlaurent@h2:/etc/netplan$ ls

I apologize if I've misunderstood. Have you manually edited the following two files using an editor like vi or nano?

・01-base.yaml
・60-mvm-mgmt.yaml

I have some concerns, such as the “interfaces” for the “mgmt” bridge being set to “eno1” instead of “vlan2”, and the “addresses” for both “mgmt” and ‘vlan2’ being the same “10.0.2.12/24”.

※Apologies if this is unclear due to machine translation.

[Ted Laurent · Accepted solution]

I agree it a bit of a hack.   However I can successfully ping the interface from my laptop as long as I set the VLAN ID correctly.   What I can't seem to do is to figure out how to enable a VM to access the VLAN.

[dya]

・HVM host: 172.16.2.111
・Manager VM: 172.16.2.110
・Management network VLAN ID: 202

Below are several potentially helpful screenshots.

Brilliant!  Thank you very much.

[dya]

I noticed I had mistakenly listed the IP addresses for the HVM host and Manager VM incorrectly, so I've made the above corrections. My apologies.

[Ted Laurent]

No worries!   The important parts were there I just needed some inspiration to put them together.   Thanks again.
