I'm trying to configure a new VLAN/Subnet on my Ubuntu 18.04 servers. I'm trying to follow the example here: https://netplan.io/examples/#configuring-source-routing
But when I follow that example, I can SSH into the servers via the br10 interface address. But from there, I can't ssh to the other nodes via either the br10 or br11 interface. Additionally, the Kubernetes cluster running on the Servers can no longer communicate with the other components. The problem that I'm trying to solve is that when users connect to a service running on the br11 interface, the response packet is going out over the br10/VLAN10 interface and being dropped by the network.
Here is my netplan configuration:
network:
version: 2
renderer: networkd
ethernets:
eth0:
addresses: []
dhcp4: false
dhcp6: false
eth1:
addresses: []
dhcp4: false
dhcp6: false
bonds:
bond0:
interfaces:
- eth0
- eth1
dhcp4: false
dhcp6: false

lacp-rate: fast
mii-monitor-interval: 100

vlans:
vlan10:
id: 10

dhcp4: false
dhcp6: false
vlan11:

dhcp4: false
dhcp6: false

br10:

table: 10
br11:
interfaces:
- vlan11
addresses:
- 10.0.11.2/24
nameservers:
addresses:

search:

dhcp4: false
dhcp6: false
routes:

via: 10.0.11.1
table: 11
routing-policy:
- from: 10.0.11.0/24
table: 11
What am I doing wrong? What's the "right" way to do ensure response packets are routed out the same interface that they arrived on?
Thanks!
