I'm trying something strange and funky in a lab and of course ending
I'm trying to configure OpenContrail to peer with ASR9K.
I've already found a sample configuration for ASR903 but that one has
Does anyone know if there is an equivalent for the following commands
So far I can't find anything and am knocking my head against the wall
did find that MGRE should be supported though and MPLS over it).
l3vpn encapsulation ip MGRE
transport ipv4 source GigabitEthernet0/4/7
route-map SELECT_UPDATE_FOR_L3VPN permit 10
set ip next-hop encapsulate l3vpn MGRE
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
-but the guide is for CSR and I haven't found anything relevant on
I have a feeling that in the end my struggle would bring more headaches
The light at the end of the tunnel is not clearly visible :)
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 suspect this was not tested with IOS XR or at least from what can be
via the Opencontrail site.
I really like the main idea of Contrail (or tungsten) - MPLS L2/L3VPNs
the way down to VMs, but the execution is terrible.
Why MPLSoUnicorns?? -and then you got to have this nonsense at the DCI
trying to stitch whatever crazy overlay encapsulation DC folks come up
with the good old MPLS VPNs in the core (it makes my life miserable).
Totally agreed but you know, it's this crazy industry push..does not
If you have the chance (new DC POD, green-field deployment), then go
the unified fabric - MPLS from DC-to-Core-to-Aggregation it's very easy
deploy and you'll love it.
No green-field but rather a PoC with this mixed setup..not too much
flexibility to go around.
And then if you want to do the contrail thing just spin up vMX or
the compute hosts -this way you can build your DC fabric using very
P-router type switches.
And if VMx or XR9000v eats too much resources on your Host then you can
the proper contrail thing but instead of vRouter you can program OVS
the ODL (yes the same SDN controller you use for the MPLS core -aint
nice) to do the L2/L3VPN label pushing/popping.
Just waiting for the DC world to wake up and realize Frame-Relay et al.
dead -that's why we have MPLS now.
:)) I'm just wondering what other crazy thing will follow and re-invent
Thanks for the long, detailed e-mail and for all the help!!
