Hi Michael,

Unfortunately, there isn't any released version of JUNOS that supports RFC8092.  When the RFC was published back in February, I let our account team know that this is important to us.  An update I got recently is that it is on the roadmap for a future, high numbered JUNOS release.  See:  http://largebgpcommunities.net/implementations/

Internet2 is currently using 13.3 for the core network.  We are looking at 15.1 deployment for support of the MPC7-MRate line cards in the near future.  I'm not aware of any plans for RFC8092 in 15.x code.

If RFC8092 looks valuable to you too, let your vendors know.

While reviewing the list of BGP communities supported by Internet2 in order to do some traffic engineering (6500[1-3]:<peerASN>) for AS path prepending, I noticed that, quite understandably, these are currently limited to two-octet ASNs.  RFC 8092, BGP Large Communities, was published earlier this year to handle tagging with four-octet ASNs.  Two questions come to mind:

1) Do (the collective) we need to develop a schema for using large communities and

2) Does the code currently running on the Internet2 routers support RFC 8092?

If the answer to 1) is 'yes' and the answer to 2) is 'no', when might we expect that capability in the backbone?

I understand this might not happen immediately because of some other projects going on.
