Can anyone share a configuration with Calico and MetalLB Layer3?

Can anyone share a configuration with Calico and MetalLB Layer3?

This what I have so far:

Router configuration (SRLinux)

--{ running }--[ network-instance ip-vrf1 protocols bgp ]--

A:border# info

    autonomous-system 65200

    router-id 6.5.2.1

    group BGP-metalLB {

        admin-state enable

        export-policy export-all

        import-policy import-all

    }

    neighbor 192.168.101.20 {

        peer-as 65201

        peer-group BGP-metalLB

    }

    neighbor 192.168.101.21 {

        peer-as 65201

        peer-group BGP-metalLB

    }

    neighbor 192.168.101.30 {

        peer-as 65201

        peer-group BGP-metalLB

    }

[ctl-a1 ~]# cat metallb-config.yml

apiVersion: v1

kind: ConfigMap

metadata:

  namespace: metallb-system

  name: config

data:

  config: |

    peers:

    - peer-address: 6.5.2.1

      peer-asn: 65200

      my-asn: 65201

    address-pools:

    - name: default

      protocol: bgp

      addresses:

      - 192.168.110.0/24

I am not receiving routes from nodes.

Not sure if Calico is interfering.

Thanks,

Mau

Finally I made it work with Nokia SRL routers with an alternative solution to what is proposed in the site, to keep using the ToR ones.

I have to change the image of the container in the metallb installation manifest though

You can see details here: https://www.cloud-native-everything.com/calico-and-metallb-working-together-with-bgp/

Best,

Cool it is working!

You can find other examples of calico with metalLB here:
https://github.com/kinvolk/lokomotive (see Equinix Metal platform,
there we use MetalLB). However, calico doesn't connect to the ToR
switch, so there is really no problem and it just works. But in case
it is useful for some other reason for you :)

Awesome, thanks man!

Now I am trying to setup ECMP with MetalLB. Let you know how it goes

[Rodrigo Campos]

It works just fine, you can advertise from several speakers and it
works out of the box. The setup there in Equinix Metal advertises from
multiple peers and then Equinix MEtal routers do ECMP.
