OpenWrt VMWare ESXi 6.7 & VLANs

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello All,

I'm looking to virtualize OpenWRT in my ESXi 6.7 server and have a couple of questions.
So far I have OpenWRT 19.07.3 r11063 booting up just fine. I threw a number of virtual interfaces at it and at least one of them actually pulls an IP (I don't know why the others don't, but that's not a major concern at the moment). I have a quad interface nic that I passthrough to the VM and OpenWRT sees it without issue.

I next took the interfaces I passed to the vm and bonded them via this:
1 - https://openwrt.org/packages/pkgdata/kmod-bonding
2 - https://forum.archive.openwrt.org/viewtopic.php?id=69209

root@OpenWrt:~# cat /etc/rc.local
# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.
ifconfig bond0 down
echo 802.3ad > /sys/devices/virtual/net/bond0/bonding/mode
#echo balance_rr > /sys/devices/virtual/net/bond0/bonding/mode
echo fast > /sys/devices/virtual/net/bond0/bonding/lacp_rate
echo layer3+4 > /sys/devices/virtual/net/bond0/bonding/xmit_hash_policy
ifconfig bond0 up

echo +eth3 > /sys/devices/virtual/net/bond0/bonding/slaves
echo +eth4 > /sys/devices/virtual/net/bond0/bonding/slaves
echo +eth5 > /sys/devices/virtual/net/bond0/bonding/slaves
exit 0
root@OpenWrt:~#

All seems to be working as expected as I see bond0 in addition to the other interfaces I expect to see.

The issue I am experiencing is that I don't know how to create VLANs (and associated dhcp/dnsmasq/etc) and trunk them to my bond0 interface. Anyone with insight as to how to do this, please?

On the other end of those interfaces will be a Brocade 6450-48P Switch.

There is no "Switch" option under "Network" in luci.

Thank you in advance.

  • Only eth1 would get an IP, as it's the WAN with a DHCP Client by default
  • eth0 is LAN and is a DHCP Server by default
  • All other NICs are unconfigured
  • Go to Interfaces and Add.
  • Specify a new ethx.x, etc.
  • Then configure its DHCP attributes
  • Add to a firewall zone

(I assume you did this for the other NICs already.)

Because you have [virtual] NICs, not a [hardware] switch. :wink:

(The problem it seems you're describing, I'd solve in VMWare.)

Thank you for the explanation!

(The problem it seems you're describing, I'd solve in VMWare.)

I'd love to know how to do it better, if you can explain a bit more, please.

It's a VMWare thing, not OpenWrt...

I'll be honest, I need more clarity on what you're tying to solve with the bond interface...your Host, etc. (which seems more like a VMWare config than OpenWrt).

Because, in my case, I'd just assign the correct VLAN to the NIC (in VMWare), simple.

I don't use pass-thru, though, I actually use VMWare to VLAN.
