How to reproduce
Expect get_if_hwaddr("vlan0") to return 10.0.2.7, instead we see 0.0.0.0:
vlan_ifaces_list=["vlan1", "vlan0"]
for iface in vlan_ifaces_list:
print(f"get_if_hwaddr({iface}) \t{get_if_hwaddr(iface)}")
print(f"get_if_addr({iface}) \t{get_if_addr(iface)}")
>>>
get_if_hwaddr(vlan1) 00:e0:4c:68:24:00
get_if_addr(vlan1) 0.0.0.0
get_if_hwaddr(vlan0) 00:e0:4c:08:1b:1b
get_if_addr(vlan0) 0.0.0.0
read_routes() has the correct information in columns 3 and 4, but it appears to be drawing from column 2, the gateway entry if I am reading this right.
s = set() # there will be redundencies so we'll use set to remove them
for line in read_routes():
s.add(line[2:5])
s
>>>
{
('0.0.0.0', 'vlan0', '10.0.2.7'),
('0.0.0.0', 'vlan1', '10.0.2.11'),
('10.0.2.7', 'vlan1', '10.0.2.11'),
snip
}
The IPs are indicated by ifconfig:
vlan1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=6063<RXCSUM,TXCSUM,TSO4,TSO6,PARTIAL_CSUM,ZEROINVERT_CSUM>
ether 00:e0:4c:68:24:00
inet 10.0.2.11 netmask 0xffff0000 broadcast 10.0.255.255
nd6 options=201<PERFORMNUD,DAD>
vlan: 2 parent interface: en7
media: autoselect (1000baseT <full-duplex>)
status: active
vlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=6063<RXCSUM,TXCSUM,TSO4,TSO6,PARTIAL_CSUM,ZEROINVERT_CSUM>

vlan: 2 parent interface: en11

Actual result
get_if_addr("vlan1") 0.0.0.0
get_if_addr("vlan0") 0.0.0.0
Expected result
get_if_addr("vlan1") 10.0.2.11
get_if_addr("vlan0") 10.0.2.7
