Can't report from production, but we have a 8201-32FH (Q200/Gibraltar) in the

right now. Currently considering it as a successor for 400G deployments
where we had NCS55A1-24H for 100G before.
So far so good for our use case as a basic PE. (unicast/multicast v4/v6,

Exactly. For example, we do all our netflow 1:1 off a fiber tap on external
appliances,
so we see all the traffic on the wire even those packets that are not forwarded
or dropped locally.
That sometimes is a bit confusing as well :)

Hi Adam,
The NCS540 has a Broadcom Qumran AX chipset with 3GB deep buffers. Smaller
brother of the Qumran MX used in the NCS5501-SE.
There should be a model coming with 4x100G around Q3 this year, which will make
it a great successor for the ASR920, especially since it has deep buffers.

Hi David,
uRPF on the NCS5500 is a mess due to limitations of the Jericho chipset.
It has to do with the TCAM optimizations and twice the number of route
lookups needed for uRPF (src/dst)
From what I understand:
On SE-models for uRPF to work you need to disable double-capacity mode

Considering that the MX10003 is a worthy alternative to many current ASR9k 100G
deployments that is way cheaper, I think it's still of interest to many Cisco
users.
Even if it is just a good reason for demanding higher discounts on your next
purchase of 100G ASR9k gear ;-)

The 3rd-Gen (EA) Trio chip is actually rated at 480G, has been rate-limited to
240G in MPC7e and MPC8e linecards and
is currently rate-limited to 400G in the MPC9e cards and the 10003 MPC.
I have no idea why it is rate-limited but suspect thermal issues?
See the book Juniper MX Series, 2nd
Regarding CWDM/DWDM, you could always add a QFX5110-48SH as a port extender box
to the MX204 with Junos Fusion Provider Edge and sacrifice one or two 100G
QSFP28 ports on the MX204.
That way you'd have 2x100G and 48x 1/10G SFP+ ports with a bit of
oversubscription in 2RU.

Hi,
What Brian hinted to is how we do it in our network. MPLS is only used for
EoMPLS/VPLS traffic,
the rest is routed via normal IP. We have dedicated /32s Loopbacks for the
EoMPLS/VPLS endpoints
and only traffic to those /32s are labeled and MPLS switched.

They have a nasty little BGP bug that can create black holes or loops
