Netflix spam after open connect appliance upgrade

[Jürgen Jaritsch]

Anyone else receiving update/upgrade notifications (after an open connect 
appliance upgrade) more than one time?

cdn-...@netflix.com is not responding so I try to 
reach someone from Netflix via NANOG ... if there's someone reading my message 
please contact me offlist.


Thanks & best regards

APC vs UPC?

[Lorell Hathcock]

NANOGians:

APC wins!

My real question is surrounding the connection on the SFPs themselves. 

In general terms are the LC connectors on SFPs considered UPC or APC?

If the answer is UPC and if I am inheriting and/or building a network of single 
mode fiber with APC SC connectors, then is the best practice to use LC UPC to 
SC APC fiber jumpers?

If so, can anyone point me to a source for said jumpers that is (1) quick and 
(2) good?

Any thoughts on the same idea of mismatched fiber jumpers connector types to 
use on OLMs and OLSs?  OTDRs?  The concern here is to use the best possible 
fiber connector types (e.g. APC or UPC) when connecting lasers to my OSP fiber 
which uses APC with consideration to the optimal connector type for the laser 
transceiver. 

My thoughts are to use fiber jumpers with UPC connectors on the laser side with 
APC on and throughout the OSP, but if it should be purely APC everywhere, then 
that is what I need to know. 

Thanks!

Hi

SFP modules will generally have UPC connectors. You therefore need to use
cables with UPC at one end and APC at the other end.

If you use a APC-APC cable you will have 3-6 dB of optical loss. If it is a
short connection and you are out of correct cables, it will usually work.
On longer connections you need the extra power budget.

As to where to buy, I will suggest fiberstore.com.

Regards,

Baldur

Most SFP/XFP have upc connectors until you get above 5(ish) db of power,  then 
you'll start to see APC and/or E2000 connections.   You'll end up using a  
hybrid jumper (APC one end,  UPS on the other).  If you're looking for quality 
jumpers look at Clearfield or Corning. ADC makes tracelite jumpers that 
illuminate if that's part of your  need. You should only see a .1-.2 db 
increase in loss for an APC connecter vs a UPC connector.

BGP MVPN RFC6513, Section 10

[Jason Iannone]

Hi all,

I'm having trouble interpreting under what circumstance section 10 of
BGP MVPN comes into play.

The way I read this section, upon the receipt of PIM/IGMP Join to
(*,G) the Receiver Site PE does not signal Type 6 or Type 7 Joins
until a Type 5 Source Active route is received from a Sender Site PE.

If Section 10 assumes the use of ASM groups in the VPN, why develop a
Type 6 Shared Tree Join A-D route for unknown sources?

What are the practical minimum Juniper configurations to support
Section 10 for ASM and (*,G) PIM Join when the PE doesn't know a
source?

CE1---PE1,C-RP-P-PE2---CE2
Sender Site---Receiver Site

1. CE1 has no active source
2. CE2 forwards PIM Join (*,G) to PE2 toward PE1,C-RP
3. PE2 eats PIM Join, maintains (*,G) state
4. CE1 generates Register messages to PE1
5. PE1 originates Type 5 (S,G)
6. PE2 receives Type 5 (S,G)
7. PE2 verifies existing (*,G) state
8. PE2 advertises Type 7 Join (S,G)
9. PE2 does PMSI and P-Tunnel attachment
10. PE1 receives (S,G) from PE2
11. PE1 adds PMSI to downstream interfaces
12. Multicast flow end to end
13. Achievement unlocked!

I'm least sure about steps 2 & 3.

Comprehension challenged,

Jason
