[j-nsp] Using a QFX5100 without QFabric?

[Alain Hebert]

     Without ASCII art:

         We have P(MX), a P(vMX), a PE1 (QFX5100), and PE2 (QFX5100), 
all with ISIS, MPLS, RSVP/LDP, BGP underlay, cluster and multipath.

         The (EVPN) broadcast is handled by the P's but once that 
discovery is done, the traffic passes between the PE's without bouncing 
thru the P's.

         Good enough for what it is.


     Must be the same deal with VPLS.


     Caveats: Can't mix EVPN and/or L2 and/or CCC on the same port.  
Right now EVPN+CCC works for our lab, but it must be a fluke.
