Static ARP is not applied on boot
Open, Requires assessmentPublicBUG

Description

VyOS 1.3-rolling built on 2020-03-19

Simple setup:

set protocols static arp 23.23.23.2 hwaddr '0c:c4:7a:93:c7:8a'
set protocols static arp 24.24.24.2 hwaddr '0c:c4:7a:93:c7:8b'

At boot-up (and after an attempt at TRex trying to use them):

vyos@vyos:~$ arp -a
? (24.24.24.2) at <incomplete> on eth2
_gateway (10.21.21.1) at 00:00:5e:00:01:15 [ether] on eth0
ec2-23-23-23-2.compute-1.amazonaws.com (23.23.23.2) at <incomplete> on eth1
vyos@vyos:~$

To fix:

delete protocols static arp
commit
set protocols static arp 23.23.23.2 hwaddr '0c:c4:7a:93:c7:8a'
set protocols static arp 24.24.24.2 hwaddr '0c:c4:7a:93:c7:8b'
commit

After:

vyos@vyos# arp -a
? (24.24.24.2) at 0c:c4:7a:93:c7:8b [ether] PERM on eth2
_gateway (10.21.21.1) at 00:00:5e:00:01:15 [ether] on eth0
ec2-23-23-23-2.compute-1.amazonaws.com (23.23.23.2) at 0c:c4:7a:93:c7:8a [ether] PERM on eth1
