Are we ok to move the route targets section out of the AF specific location to 
where RD is specified? If so, we can define the following common grouping:

RD and RT. So that we can retain AF level granularity for RT grouping for

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

3 Yang models.

  | +--rw bgp-parameters
  | |  +--rw common
  | | +--rw rd-rt* [route-distinguisher]

It will be interesting to create a common BGP parameter Yang module as shown

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.

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.

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-distinguisherstring
  | |+--rw vpn-target* [rt-value]
  | |   +--rw rt-valuestring
  | |   +--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

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.
