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

@c-po is it possible to detect the exact networking setup used on the host? 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

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

An issue to change the MTU should not fail the whole interface change but just this one but the code does not not allow this easily. I will try to work on this.
