Hi Alex,

You are correct.  This model does not define any VLAN based forwarding by itself, that is entirely left to other models.


The options available today are:


IETF:

- Use this model in conjunction with IPv4/IPv6 YANG models for L3 routed traffic.

- Use this model in conjunction with an L2VPN YANG model (e.g. draft-ietf-bess-l2vpn-yang-08), or perhaps also with draft-ietf-bess-evpn-yang-05.


IEEE:

- Use the IEEE 802.1 bridging YANG model (which isn't based on sub-interface constructs at all).


OpenConfig:

- They have a hybrid model that supports both L2VPN based services and basic VLAN based switching.


Thanks,
Rob

Hi,


I'm currently looking at draft-ietf-netmod-sub-intf-vlan-model-03 to see whether we can use this as our main model for VLAN forwarding, and it appears the answer is no. There is no way to configure forwarding in this model; it is strictly about interfaces.


The appendix gives the impression that this model can be used to configure forwarding, though: "Both models can be used for configuring similar basic layer 2 forwarding topologies,"

Is forwarding configuration out of scope of this model?


Thanks,

  Alex
