L7 loxilb setup

[chugh50]

I am trying to setup L7 loxilb loadbalancing for my amf pods .So i am running two amf pods using replicaset and also configure loxilb with the L7 image and use the following serivce

kind: Service
metadata:
name: amf-loxilb-service
#namespace: kube-system
annotations:
loxilb.io/liveness: "yes"
loxilb.io/usepodnetwork : "yes"
loxilb.io/lbmode: "fullproxy"
loxilb.io/epselect: "n2"
loxilb.io/probetype: "none"
loxilb.io/staticIP: "10.10.19.69"
#loxilb.io/sticky-sessions: "false"
spec:
loadBalancerClass: loxilb.io/loxilb
selector:
#what: amf-app
app.kubernetes.io/instance: amantyals
app.kubernetes.io/name: helm-amf
ports:

• port: 38412
  targetPort: 38412
  protocol: SCTP
  type: LoadBalancer
  externalTrafficPolicy: Local
  sessionAffinity: None

Whenever i try to send any request (like sctp connection ,ngsetup) from one gnB it should route to one of the amf but in my case it is routing to both the amf

If someone have idea about this issue please let me know
Thanks

In this mode, the node specific messages are sent to all the available AMFs but UE registration etc is load-balanced to specific AMF.

Hi @UltraInstinct14 Thanks for the input i rechecked as you mentioned but UE registration request is also routing to both amf pods

LoxiLB L7 currently supports NGAP in ASN.1 APER (aligned Packed Encoding Rules) format only. Can you please confirm in your setup ? And are you using this image : ghcr.io/loxilb-io/loxilb:scp ?

[chugh50]

yes in my setup i am using NGAP in ASN.1 APER and i used the same image only

I tried a similar setup. The loxilb yaml as follows -

containers:
      - name: loxilb-app
        image: "ghcr.io/loxilb-io/loxilb:scp"
        imagePullPolicy: Always
        command:
        - /root/loxilb-io/loxilb/loxilb
        args:
        - --proxyonlymode
        - --blacklist=cni[0-9a-z]|veth.|flannel.|cali.|tunl.|vxlan[.]calico|kube[-]bridge

LB rules -

| 192.168.80.250 |         |      | 38412 | sctp  | amf:llb-inst0                |    0 | n2  | fullproxy | 172.16.219.106 | 38412 |      1 | -     | 14:942   |
|                |         |      |       |       |                              |      |     |           | 172.16.219.121 | 38412 |      1 | -     | 2:126    |

Observations -

NGsetup and other node messages are sent to all AMFs but UE messages like InitialUE message are send to a particular AMF only.
