I agree that the Keepalivd SMTP implementation is lacking authentication.

@Viacheslav I may be on to something. It's related to the order of execution of the DHCP client exit hook scripts in /etc/dhcp/dhclient-exit-hooks.d.

Actually only multihop BGP peers go down. Others are up, but the routes received from them does not go to kernel, so the connectivity drops.

The system was alive more than 12 hours, but crashed the same way as before.

I don't think this ever worked as intended: see T3275#103228, vyos-build PR 185, and T3821.

after an internal discussion we came to the conslusion that keepalived SMTP implementation is incomplete (e.g. it lacks authentication). In order to still support your request we think we should enable support of 3rd party configurations placed in e.g. /etc/keepalived/conf.d.

@sdev just for clarification do you mean "deleted" as in only existing entries but new ones will work or completely deleted?
Im asking because I do use keas global, subnet, pool and class option-data support extensively outside of vyos.
If this would stay/become a part of vyos that would be great!

Wanted to have the ticketid to write the right commit message right away. Diff is here: https://github.com/vyos/vyos-1x/compare/current...ichdasich:vyos-1x:filtered_routes

If we add vlan to range we get error

set service ipoe-server authentication mode 'noauth'
set service ipoe-server client-ip-pool name POOL1 gateway-address '192.0.2.1'
set service ipoe-server client-ip-pool name POOL1 subnet '192.0.2.0/24'
set service ipoe-server interface eth1 vlan '2000-3000'

@n.fort @Viacheslav
Here is an example of what I am after for DNAT rule, specifically, using meta pkttype:

QoS Policy Limiter now works correctly.
But the shaper classes for tagged traffic don't work.

I was able to get it to work as expected by reducing the lease below 4294967295 and removing the /config/dhcpd.leases file. It should work per the instruction to make the lease effectively static. It had worked in the past so at some point the check that the resultant lease end day is numeric.

Example configuration:

My bad
