Doug,
Thank you very much. Looking over this config now, I’m hoping it
will help me figure out what I’m missing. It may have something to do with the
MGRE tunnels.
Thanks again!
Jay

I don't speak Nokia but here is a Cisco CSR example I got working a while ago.
Maybe it will be easier for you to understand than a Juniper config?
You are basically setting up dynamic MGRE tunnels to the compute nodes and a
VRF for onramp/offramp into the cluster. The Contrail controllers are
advertising L3VPN routes via BGP to the gateway. You'll need a public VRF for
onramp / offramp of public traffic. A small 'backplane loopback network"
connects that VRF to the global table. The gateway learns about the tenants and
sets up a route with a GRE tunnel to a specific compute node as the next hop.
MPLS tags are inside the GRE tunnels to isolate different virtual networks from
each other.
HTH,
Doug

Subject: Suspected SPAM - [opencontrail-dev] Opencontrail interoperation with
Nokia 7750 Services Router or other routers
Hello!
I’ve been trying to connect our opencontrail 3.0 setup to an
external router to allow communication items outside the openstack cloud. I
understand that the OpenContrail vRouters support MPLS over GRE, MPLS over UDP,
and VXLAN for this type of communication. I’m trying to do this with a Nokia
7750 Services Router, but I have been unsuccessful. I can get the BGP talking
between the OpenContrail controller and the router, but I can’t get the routes
into the route table or any traffic to pass. I really don’t understand how the
OpenContrail expects its MPLS / VXLAN to be setup. The only practical example
I can find is the following link which is over 2 years old:
http://www.opencontrail.org/how-to-setup-opencontrail-gateway-juniper-mx-cisco-asr-and-software-gw/
Is there any more information on how to set this up? Or any
more examples of real configuration? I’d love an actual Nokia 7750 Services
Router example, but I would take anything that might help me better understand
the setup.
Thank you very much!
Jay
