Description

Unable to get LB to both pools in the separate namespaces.

Steps To Reproduce

1) Deploy ab vs with differing weights 2) Test with client hitting the vip 3) Notice that only the first rule is hit, only the alternatebackend is displayed

Expected Result

I get LB to both pools

Actual Result

I only get LB to the alternate backend pool

Diagnostic Information

vs

apiVersion: cis.f5.com/v1
kind: VirtualServer
metadata:
  labels:
    f5cr: "true"
  name: vscafebg
  namespace: blue
spec:
  virtualServerAddress: 2000:abcd:105:c::1001
  tlsProfileName: edge-tls
  httpTraffic: redirect
  host: bgcafe.example.com
  pools:
    - path: /
      service: nginxsvcbg
      servicePort: 80
      weight: 70
      alternateBackends:
        - service: nginxsvcbg
          weight: 30
          serviceNamespace: green

Observations (if any)

If I create virtualServer just for each of the namespaces separately, I can access the backend pods correctly.

In my LTM policy I see 3 identical rules, is this normal?:

vs_bgcafe_examplecom vs_bgcafe_example_com_nginxsvcbg_80_blue_bgcafe_example_com vs_bgcafe_example_com_nginxsvcbg_80_green_bgcafe_example_com

each with conditions: HTTP Header full string named 'host' is 'bgcafe.example.com:443', or 'bgcafe.example.com' at request time. and logs: Log message 'a/b pool' at request time.

bigip ltm logs show below that only the first rule gets hit I believe:
