Always exclude this address from any defined range. This address will never be assigned by the DHCP server.
Ok, it will exclude in any range.
Forget about it

I don't see any problem on user receive message telling him MTU is not accepted by OS when his commit
On Juniper it is very common case
My suggestion: if you do a MTU suggestor/validation should be a tool optional outsite configure

great work @thomas-mangin I was reading your code
Hardware vendor: Red Hat
Hardware model: OpenStack Compute
MTU should be max 1450

If not, I don't think that'll do any good, because the hypervisor is just that - a hypervisor. There can be many different types of networking. Like in this case, Openstack's SDN supports a lower MTU than a bridged or NATed connection with the same hypervisor would. The only reliable way is to detect the max MTU in some way (the kernel/device driver must know this, the question how can we read it) - the first step is to not touch the default MTU if the user doesn't set it.

My suggestion:
- if someone set a higher MTU than OS support, commit fail will be ok and that's OK, each vyos admin should know his OS limitations
Other ubuntu servers inside same openstack max mtu OS leave at 1450 too
In T2404#62637, @robertoberto wrote:I tried to google to find out how to discover max mtu an interface accept but not found.
I guess limitation is because we are using OpenStack KVM or the other guy is using VMware and they use some bytes to their SDN
I tried to google to find out how to discover max mtu an interface accept but not found.
