Hi Folks,

Same here. Can we do something about it?  And agree, all 3 VPN models should have the same commonality.

Patrice Brissette

I’d prefer common grouping in draft-ietf-rtgwg-routing-types and references from any other model using it


Cheers,
Jeff

Hi Giles,
I will add the route-target-type type (enum of import, export, both) but for a general grouping, it appears there are some discrepancies between the 3 models. Assuming the types: route-discriminator, route-target, and route-target-type, can you provide a consensus grouping that all the models would use?
Thanks,
Acee

Hi Acee,

In general seems that for any BGP VPN (L2 or L3) you have an RD plus a list of RTs (which can be import, export or both) - so I’d prefer that to be defined in a shared grouping (more or less as per the structure Patrice gave below) than to force each model to redefine it.

Hi Patrice – we are working fervently on a common IETF routing types model. We have both route-target and router-distinguisher types defined there. The work is being done in the Routing WG. Our intension is to accelerate standardization so it doesn’t hold up standardization of the importing modules. Please comment as to whether you think this meets BESS requirements.

https://www.ietf.org/id/draft-ietf-rtgwg-routing-types-00.txt

Thanks,
Acee
P.S. We plan an update next week but the RD and RT definitions have not changed.

Subject: [bess] BGP common parameter Yang module

Folks,

As part of EVPN, L2VPn and L3VPN Yang model, there is a “module” common to all 3 Yang models.

      |     +--rw bgp-parameters
      |     |  +--rw common
      |     |     +--rw rd-rt* [route-distinguisher]
      |     |        +--rw route-distinguisher    string
      |     |        +--rw vpn-target* [rt-value]
      |     |           +--rw rt-value    string
      |     |           +--rw rt-type     bgp-rt-type


It will be interesting to create a common BGP parameter Yang module as shown above. I think it just makes sense.
However, there is a minor challenge; that module require a home (a draft).
I’m looking for feedback about the best place/draft for such a module.

Thanks for your help.
Regards,
Patrice Brissette
