I am trying to configure DHCP server in vyos 1.1.8 sing beow command:

vyos@vyos# set service dhcp-server shared-network-name ESX-VTEP subnet 172.16.40.0/24 default-router 172.16.40.1
[edit]
vyos@vyos# set service dhcp-server shared-network-name ESX-VTEP subnet 172.16.40.0/24 start 172.16.40.11 stop 172.16.40.111
[edit]
vyos@vyos# set service dhcp-server shared-network-name ESX-VTEP subnet 172.16.40.0/24 lease 86400
[edit]

When I do a commit and save, I am getting below error

vyos@vyos# commit
[ service dhcp-server ]
DHCP server error: None of the DHCP lease subnets are inside any of the subnets
configured on broadcast interfaces. At least one DHCP lease subnet must be set
such that DHCP server listens on a minimum of one broadcast interface
DHCP server configuration commit aborted due to error(s).

[[service dhcp-server]] failed
Commit failed

Any suggestions on how to fix this.

do you have an interface configured with an IP address in 172.16.40.0/24?

If so which kind of interface?

Hmm, as well as what @Jeff pointed out, memory is hazy if this is a new config and you havent commited after creating the interfaces?
If you havent and are trying to create the DHCP server on interfaces that are not yet commited (so dont exit) it may not work.
I havent tested this before I commented, but recall some limitations when I originally set up a while ago. Worth a test if you are in the boat above anyways…
