Hi Naveen, We faced the same issue when moving interfaces between VRFs. This commit helped - https://github.com/FRRouting/frr/commit/c6982533ba5769a590d089fa1eebf17a7ec0... Igor On Tue, Jan 14, 2020 at 5:30 AM Naveen K Suvarna via dev < dev@lists.frrouting.org> wrote:

Hi All,

In FRR 7.2, I am seeing interface command Failures as below. This is happening randomly. Once system goes in to this state, failure happens for all interfaces.

Is this a known issue ? Is there any fix for this ?

*dut4(config)# interface Vlan2*

% Configuration failed: validation error.

Please check the logs for more details.

dut4(config)# interface Ethernet0

% Configuration failed: validation error.

Please check the logs for more details.

*dut4(config)# interface Ethernet0*

% Configuration failed: validation error.

Please check the logs for more details.

dut4(config)# interface Vlan2

% Configuration failed: validation error.

Please check the logs for more details.

*dut4(config)# *

Not much logs generated, except below.

Call to if_lookup_by_name_all_vrf(ifname) Fails leading to below error
