Here is an example netplan yaml that emulates this configuration in a
test container.
network:
version: 2
ethernets:
eth0:
dhcp4: false
bonds:
bond0:
interfaces: [eth0]
parameters:
mode: active-backup
arp-interval: 10
vlans:
bond0.100:
id: 100
link: bond0
addresses: [10.44.49.39/24]
routes:
- to: 0.0.0.0/0
via: 10.44.49.1
Setting 'arp-interval' causes the link to drop after a short period
because the lxd bridge for the container isn't configured compatibly; so
I've removed that line for testing here.
However, I haven't understood why you have addresses assigned on both
the bond and the vlan, or what you're intending to achieve by
reconfiguring the bond with nmcli. Here, the links appear to work as
expected when managed directly with iproute2.
# ip -4 addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group

I don't see anything here to indicate the kernel is mishandling these
interfaces.

A debugger is not configured
---Steps to Reproduce---
1. Created a network bond with static IP address (and no IPv6 address);
active backup mode; ARP polling; single slave.
2. Created a VLAN using said network bond with static IPv4 address
(and no IPv6 address).
3. Can ping from the appliance to a target on both links (the parent
bond and the VLAN).
4. Switched to another slave for the created bond
5. Can still ping from the appliance to a target via the parent bond;
however, cannot ping to the target via the VLAN.
=============================================================================
Detailed steps:
1. Initial setup:
============
root@S36MANDAR:~# nmcli c s
NAME UUID TYPE DEVICE
enc1a80 c3a2037d-60a3-3cb4-9234-45aed55f7093 ethernet enc1a80
enc8f00 2423add6-1464-3765-877c-a214dc497492 ethernet enc8f00
enc1d40 ff2d70f8-130e-3dc6-ab24-1dba07563605 ethernet --
2. Create Netwrok-bond with one slave:
================================
root@S36MANDAR:~# nmcli c add type bond con-name mybond1 ifname mybond1
ipv4.method disabled ipv6.method ignore
Connection 'mybond1' (4b918a65-43a6-4ec3-b3c4-388ed52b116d) successfully
added.
root@S36MANDAR:~# nmcli con add type ethernet ifname enc1d40 master mybond1
Connection 'bond-slave-enc1d40' (cfe4b245-3dda-4f45-b7b4-6d40d144a02f)
successfully added.
root@S36MANDAR:~# nmcli con up bond-slave-enc1d40
Connection successfully activated (D-Bus active path:
/org/freedesktop/NetworkManager/ActiveConnection/18)
root@S36MANDAR:~# nmcli c s
NAME UUID TYPE DEVICE
bond-slave-enc1d40 cfe4b245-3dda-4f45-b7b4-6d40d144a02f ethernet enc1d40
enc1a80 c3a2037d-60a3-3cb4-9234-45aed55f7093 ethernet enc1a80
enc8f00 2423add6-1464-3765-877c-a214dc497492 ethernet enc8f00
mybond1 4b918a65-43a6-4ec3-b3c4-388ed52b116d bond mybond1
enc1d40 ff2d70f8-130e-3dc6-ab24-1dba07563605 ethernet --
3. Create vlan over mybond1:
=======================
root@S36MANDAR:~# nmcli con add type vlan con-name vlanbond.100 ifname
vlanbond.100 dev mybond1 id 100 ipv4.method disabled ipv6.method ignore
Connection 'vlanbond.100' (e054df42-97a0-492b-b2c9-b9571077493e) successfully
added.
root@S36MANDAR:~# nmcli c s
NAME UUID TYPE DEVICE
bond-slave-enc1d40 cfe4b245-3dda-4f45-b7b4-6d40d144a02f ethernet enc1d40
enc1a80 c3a2037d-60a3-3cb4-9234-45aed55f7093 ethernet enc1a80
enc8f00 2423add6-1464-3765-877c-a214dc497492 ethernet enc8f00
mybond1 4b918a65-43a6-4ec3-b3c4-388ed52b116d bond mybond1
vlanbond.100 e054df42-97a0-492b-b2c9-b9571077493e vlan
vlanbond.100
enc1d40 ff2d70f8-130e-3dc6-ab24-1dba07563605 ethernet --
4. Reactivate bond :
=================
root@S36MANDAR:~# nmcli con up mybond1
Connection successfully activated (master waiting for slaves) (D-Bus active
path: /org/freedesktop/NetworkManager/ActiveConnection/30)
root@S36MANDAR:~# nmcli c s
NAME UUID TYPE DEVICE
enc1a80 c3a2037d-60a3-3cb4-9234-45aed55f7093 ethernet enc1a80
enc1d40 ff2d70f8-130e-3dc6-ab24-1dba07563605 ethernet enc1d40
enc8f00 2423add6-1464-3765-877c-a214dc497492 ethernet enc8f00
mybond1 4b918a65-43a6-4ec3-b3c4-388ed52b116d bond mybond1
bond-slave-enc1d40 cfe4b245-3dda-4f45-b7b4-6d40d144a02f ethernet --
encw1810 4ddeb38e-d5f7-3814-abb7-be50b8da874e ethernet --
vlanbond.100 e054df42-97a0-492b-b2c9-b9571077493e vlan --
As is seen, vlan(vlanbond.100) did not get activated
Now, if manually I make vlan connection up, it gets activated:
root@S36MANDAR:~# nmcli con up vlanbond.100
NAME UUID TYPE DEVICE
bond-slave-enc1d40 cfe4b245-3dda-4f45-b7b4-6d40d144a02f ethernet enc1d40

enc8f00 2423add6-1464-3765-877c-a214dc497492 ethernet enc8f00
mybond1 4b918a65-43a6-4ec3-b3c4-388ed52b116d bond mybond1
vlanbond.100 e054df42-97a0-492b-b2c9-b9571077493e vlan
vlanbond.100
enc1d40 ff2d70f8-130e-3dc6-ab24-1dba07563605 ethernet --
encw1810 4ddeb38e-d5f7-3814-abb7-be50b8da874e ethernet --
