Test results on the VyOS 1.3-rolling-202004020117:
Basically, the DHCP option 121 is handled as expected but two issues were observed i.e.:

1. Static routes advertised by the DHCP server in option 121 are not automatically removed from the FIB when the "address dhcp" setting is removed from the interface. Disable/enable the interface doesn't change anything. The only option to get rid of them is to restart the router.

A similar behavior is observed when the "address dhcp" config is replaced with static IP address in one go. In that case disable/enable the interface at least makes them removed from the FIB but they are still present in the FRR as "inactive" . The only option to get rid of them is to restart the router.

decided to go with HAProxy

Trying to find more information with debugging settings of zebra process.

Thanks very much, @jestabro !

@chrismarget I'll commit the changes shortly, and close the task; thanks!

c-po closed PR#100 based on intent to restore (I didn't realize they'd been removed) those packages via the dockerfile.

Tested on 1.2.5

There are no other reports about such issues
we need valid reproduction procedure for this, otherwise, not much that we can do

https://github.com/vyos/vyos-1x/pull/335

could you please try this patch. if it still fails, can you remove the 'mtu' from the 'options' line and try again ?
