SONiC Support

[Gerrit91]

• Sample repository with Containerlab (2 spine + 2 leaf topology + 2 machines) --> communication between 2 machines is possible through EVPN overlay network
  • Deciding for SONiC distro (Edgecore / Broadcom / Vanilla)
• Migration of current Cumulus configuration to equivalent SONiC configuration
• Implementation into metal-stack
  • Adapt mini-lab (metal-core, deployment playbooks)

Points for further investigation:

• Default tx-interval for lldp is 30 seconds and can only be changed via lldpcli. https://github.com/Azure/sonic-buildimage/blob/202111/dockers/docker-lldp/lldpd.conf.j2
• Setting configure lldp portidsubtype macaddress via lldpcli has not the desired effect:
  2022-06-08T11:46:01.326Z debug lldp {"detectedNeighbor": "Name:mini-lab-leaf02 Desc:SONiC Software Version: SONiC.HEAD.0-dirty-20220603.064718 - HwSku: Force10-S6000 - Distribution: Debian 11.3 - Kernel: 5.10.0-8-2-amd64 Chassis:Mac:a2:85:c9:17:52:9c Port::"}

lldpgrmd reacts on changes in the Redis database and configured the portidsubtype to local. It used the alias field from the PORT definitions.

We can use config replace <file> in metal-core to reload the whole configuration, but it works only for versions that contains Yang support for VXLAN.

Support for SONiC was release in metal-stack v0.14.0.
