ASR9k does support mGRE but only in Draft-Rosen-MVPNs.
-so the tunnel endpoints and the necessary overlay encapsulation is all
determined via BGP (so no route-maps or NHRP).
You could try to follow this guide:
and just substitute L2TPv3 with GRE encapsulation and see how far you can
-but the guide is for CSR and I haven't found anything relevant on L2TPv3 on
Well you should ask Juniper folks as they claim vendor neutral support
-would like to see how they tested this with XR :)
Most likely p2p GRE.
I really like the main idea of Contrail (or tungsten) - MPLS L2/L3VPNs all
the way down to VMs, but the execution is terrible.
Why MPLSoUnicorns?? -and then you got to have this nonsense at the DCI PEs
trying to stitch whatever crazy overlay encapsulation DC folks come up with
with the good old MPLS VPNs in the core (it makes my life miserable).
If you have the chance (new DC POD, green-field deployment), then go with
the unified fabric - MPLS from DC-to-Core-to-Aggregation it's very easy to
deploy and you'll love it.
And then if you want to do the contrail thing just spin up vMX or XR9000v on
the compute hosts -this way you can build your DC fabric using very cheap
P-router type switches.
And if VMx or XR9000v eats too much resources on your Host then you can do
the proper contrail thing but instead of vRouter you can program OVS from
the ODL (yes the same SDN controller you use for the MPLS core -aint that
nice) to do the L2/L3VPN label pushing/popping.
Just waiting for the DC world to wake up and realize Frame-Relay et al. is
dead -that's why we have MPLS now.
