Hello,
This is logically correct. Since EVPN instance needs to be configured on
PE router, then we have 2 interface categories for EVPN PE router:
1/ own CE-facing - referred to below as "CE device interfaces"
2/ another PE-facing - referred to below as "PE device interfaces".
The (2) is also known as "core-facing".
I admit the wording could be made better - please open a case with JTAC
to add clarity.
HTH
Thx
Alex

I am trying to wrap my head around the following note in this doc:
http://www.juniper.net/techpubs/en_US/junos15.1/topics/example/example-evpn-multihoming-configuring.html
"Note: Prior to Junos OS Release 15.1, the EVPN functionaliy support
on MX Series Routers was limited to routers using MPC and MIC
interfaces only. However, starting with Junos OS Release 15.1, MX
Series Routers using DPCs can be leveraged to provide EVPN support on
the CE device-facing interface.
The DPC support for EVPN is provided with the following
considerations: DPCs provide support for EVPN in the active-standby
mode of operation including support for the following:
a. EVPN instance (EVI)
b. Virtual switch (VS)
c. Integrated routing and bridging (IRB) interfaces
DPCs intended for providing the EVPN active-standby support should be
the CE device-facing line card. The PE device interfaces in the EVPN
domain should use only MPC and MIC interfaces."
At first, I assume that this means that EVPN is supported as of 15.1
for DPC line cards, in PE routers that are facing CE devices.
Something that is a "CE device-facing line card" would be on a PE
router. But then that last sentence confuses me by saying talking
about "PE device interfaces" do NOT support the DPC line cards.
Does anyone have their JUNOS documentation decoder ring handy to try
to help interpret this for me?
