03/24/2023, 3:51 AMHi All , I have issue connecting my nic using multus, maclan.
Any pointers or help is appreciated.
Here is what I did.
Machine1 with eth0 is installed with k3s along with multus, fannel as default and macvlan.
From the 'samplepod' created using mvlan, I am not able to ping machine2 via net1 (network interface).
Could you please help.
Setup
Two Machines both in same subnet 10.2.0.0
Machine1 - Ip 10.2.0.4
Machine2 - IP 10.2.0.8
Setup for Machine 2 - End
Machine 2 details
$ sudo kubectl get pods -A
