Properly configure source routing on Ubuntu 18.04

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
    parameters:
      lacp-rate: fast
      mii-monitor-interval: 100
      mode: 802.3ad

vlans:
  vlan10:
    id: 10
    link: bond0
    dhcp4: false
    dhcp6: false
  vlan11:
    id: 11
    link: bond0
    dhcp4: false
    dhcp6: false

bridges:
  br10:
    interfaces:
      - vlan10
    addresses:
      - 10.0.10.2/24
    nameservers:
    addresses:
      - 10.0.1.1
      - 10.0.1.2
    search:
      - domain.com
    dhcp4: false
    dhcp6: false
    routes:
      - to: 0.0.0.0/0
        via: 10.0.10.1
      - to: 10.0.10.0/24
        via: 10.0.10.1
        table: 10
    routing-policy:
      - from: 10.0.10.0/24
        table: 10
   
  br11:
    interfaces:
      - vlan11
    addresses:
      - 10.0.11.2/24        
    nameservers:
    addresses:
      - 10.0.1.1
      - 10.0.1.2
    search:
      - domain.com
    dhcp4: false
    dhcp6: false
    routes:
      - to: 10.0.11.0/24
        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!
