SolusIO compute resource breaks the VLAN after reboot

Symptoms 

• SolusIO compute resource is part of a VLAN. After reboot the traffic inside the VLAN does not reach the hosts.

Cause

By default the proxy_arp and proxy_ndp are enabled on the Compute resource.

Resolution

1. Connect to the Compute Resource via SSH
2. Run the commands:

   # sysctl net.ipv4.conf.br-ext.proxy_arp=0
   # sysctl net.ipv6.conf.br-ext.proxy_ndp=0

3. In order for changes to apply on each reboot set 0 for the above parameters in the files /etc/sysctl.d/99-solus-proxy-ndp-br-ext.conf and /etc/sysctl.d/99-solus-proxy-arp.conf:

   # cat /etc/sysctl.d/99-solus-proxy-ndp-br-ext.conf
   net.ipv6.conf.br-ext.proxy_ndp=0
   # cat /etc/sysctl.d/99-solus-proxy-arp.conf
   net.ipv4.conf.br-ext.proxy_arp=0
