romanspb80 · 2025-01-27T00:53:03Z

Add route aggregation feature in BGP Control Plane (RFC 4632)
New route aggregation options under the CiliumBGPAdvertisement.

apiVersion: cilium.io/v2alpha1
kind: CiliumBGPAdvertisement
metadata:
  name: bgp-advertisements
  labels:
    advertise: bgp
spec:
  advertisements:
    - advertisementType: "Service"
      service:
        aggregationLengthIPv4: 24                  <<<<<<<<<<<<<<   New Field
        aggregationLengthIPv6: 120                 <<<<<<<<<<<<<<   New Field

Fixes: #36777

Hi @romanspb80 Before jumping into the code review of the implementation, I think we need to agree on the API change. I still think user should specify aggregation length instead of dynamically calculating it based on the boolean flag.

In vast majority of cases there is going to be single IP returned from getServicePrefix
, so with single /32 or /128 prefix there will be nothing to aggregate.

Have you tested this change on kubernetes cluster with sample loadbalancer service ? can you provide some example outputs how aggregation will look like?

Hi @harsimran-pabla . Thanks for the comment.
I agree with you that the most common case would be single prefix. But there are couple of points which are worth discussing.
For example, we can use annotation to assign multiple ips for serice advertisement:

apiVersion: v1
kind: Service
metadata:
  name: nginxservice
  annotations:
    "io.cilium/lb-ipam-ips": "172.16.102.2,172.16.102.8"
spec:
  type: LoadBalancer
  selector:
    app: nginx
  ports:
  - name: grpc
    port: 8888
    targetPort: 80

In this case the dynamically calculating works:

bash-5.1# ./gobgp neighbor 172.18.0.2 adj-in
   ID  Network              Next Hop             AS_PATH              Age        Attrs
   0   10.244.1.0/24        172.18.0.2           65002                00:03:05   [{Origin: i}]
   0   172.16.102.0/28      172.18.0.2           65002                00:00:05   [{Origin: i}]
bash-5.1#

The dynamically calculated mask /28 is more efficiently then if we set the mask /24 manualy.

Also there is another case which I noted in my comment :
"I would also like to note that in this pull request, aggregation is performed only for prefixes within the service. But in this PR I made a feature in which aggregation takes into account all services with this option and the route aggregation is global for all prefixes of the affected services. I suggest discussing this point too."

Thanks

Yes, but the common case is that each service gets single /32 prefix. And if we pick start and end address from various services which have aggregate flag set, resulting aggregated prefix can be very large range - as services can have IPs allocated from different lb-ipam pools.

harsimran-pabla · 2025-01-30T20:52:54Z

"I would also like to note that in this pull request, aggregation is performed only for prefixes within the service. But in this #36791 I made a feature in which aggregation takes into account all services with this option and the route aggregation is global for all prefixes of the affected services. I suggest discussing this point too."

This approach was modifying LB Pool with a aggregate flag. Why not introduce new BGP advertisement type which will advertise complete LB IPAM pool range ? Implementation would be much simpler and not change existing service reconcilers.

I am trying to understand if the goal is to reduce /32 prefix announcements, can we achieve it with this simpler mechanism. Existing service announcements can be configured if user wants to service with eTP=Local to work.

Yes, that makes sense. So instead of dynamic calculation use the cidr (or all cidrs from the LB pool) mask right away?
For example, if cidr from LB pool is 172.16.102.0/25 then bgp advertisement will be same in case of enabled aggregation.
We can also add an option for the case where the pool contains multiple cidrs, then they can be aggregated if they are adjacent.

harsimran-pabla · 2025-02-03T14:49:35Z

We can also add an option for the case where the pool contains multiple cidrs, then they can be aggregated if they are adjacent.

No, I would still prefer each pool advertisement. Atleast we should start with this common case and see later if it makes sense to improve further upon it. In this approach, feature is not about prefix aggregation. It is more about LB Pool advertisement.

harsimran-pabla · 2025-02-03T15:00:01Z

There are two approaches to reduce /32 advertisements, I am not leaning towards one or the other.

Introduce new advertisement type, which is LB Pool Advert. This will advertise LB Pool prefix regardless of checking backend services. Much simpler implementation as well as larger prefix block can be advertised. Drawback is that if you'd want services with eTP=Local, this is not enough. And other cases of cluster ip/external ip advertisement, this advertisement type is not the solution for it.
Provide prefix length as previously discussed here.

I am not yet convinced if we need to jump straight into auto-aggregation, we can look at it in the future. At this stage, I think we need something simpler and deterministic.

romanspb80 · 2025-02-03T18:53:57Z

Ok. Will do this approach:

Provide prefix length as previously discussed here.

Hi @harsimran-pabla
I've updated PR in accordance with the second approach. I added two fields:

aggregationLengthIPv4 with range 24..31
aggregationLengthIPv6 with range 120..127

It makes sense to discuss the thresholds of these ranges.

Thanks

Thanks @romanspb80 for the changes. API looks good to me, there are few other comments regarding the implementation.

Route policies should be done for all service types ( external IP, cluster IP ), currently it implemented for LB Ingress IP only.
Unit tests are missing.
Route policies which are merged here should be sorted based on prefix length. For eg, if multiple advertisements match same service, longer prefix should be first.

@cilium/sig-k8s CRD changes look good to me. I do see that @harsimran-pabla had a comment regarding the need for the min values.

@harsimran-pabla , I've updated the PR in accordance with the comments.
Thanks

romanspb80 · 2025-03-07T21:03:55Z

Hi @romanspb80, instead of merge commit, can you please rebase only your change on top of latest. merge-commit is not allowed in Cilium.

Also, we promoted the BGP APIs from v2alpha1 to v2, I see that you updated the API in v2. Similar to change in pkg/k8s/apis/cilium.io/v2/bgp_advert_types.go, you should do same change in pkg/k8s/apis/cilium.io/v2alpha1/bgp_advert_types.go, we want to keep both APIs same for time being. This helps in easy migration for users from v2alpha1 to v2.

Thank you, @harsimran-pabla . I updated the change
