[j-nsp] EVPN/VXLAN experience

[Raphael Maunier]

Hello,

For some reason, we had a lot of issue with ISIS with evpn-vxlan on Broadcom chipset.
We had a ticket running for months with Juniper about this. ECMP wasn't working, mac boucing and so on.
We moved to OSPF and ... no more issue since then. The topology was not a basic leaf-spine but a ring ( not officially supported by the SI team @juniper )

 This was on QFX5100

    We use ISIS. It's easier for people to understand and I don't expect
    any scalability issues with our size of fabrics. We did not encounter
    any drawbacks by using ISIS instead of BGP.
