Hi

have been reading cisco documentation on this topic.

I was wondering if anyone knew the JUNOS status for this was?

Cant find much on the website etc etc.

many thanks

Hey William,

RSN. 1st half of 2016. I'm sure you can get some image to play with if
you contact your account team.

Also if folks are looking for an early intro into the config and operation within Junos there is a relatively new book “MPLS in the SDN Era” from Juniper and it has quite a bit on SPRING. The other nice thing about the book is all the use cases are mixed-vendor including both Junos and IOS-XR configs.

Julian Lucek gave a very good talk and demo at the Nxtwork conference
in San Jose a couple of months ago. He was on a vMX network with
preproduction code and statically assigned label stacks in an ISIS
environment. They didn't have IGP signaled labels. From the looks of
things they're on it, but what I saw should be considered proof of
concept. He was pretty tight lipped about expected release dates.
The technology looked cool, though.

Thanks David, I should've read this email before asking my previous
question.

I just got this book yesterday. Page 92 says SPRING is aka SR. Thanks

Also I see in preface page xxii that one of the four key contributors to
this book was a guy named David Roy....is this you? :)

These topics are new to me...

I understand that SR is Segment Routing and SPRING is Source Packet Routing
in Networking... so I want to know is "SR" and "SPRING" the exact same thing
? or are there some differences in SR and SPRING ?

Yes this exactly the same thing. Just naming. Cisco uses more SR and Juniper SPRING :)

But IETF says SPRING

I am working my way through _MPLS in the SDN Era_, and I really am
intrigued by what I read about SPRING.

I got burned a few years ago trying to deploy RSVP for traffic engineering
purposes, and I ran into so many serious JUNOS bugs, I had to abandon it
and use LDP to handle labels and stick with IGP metric manipulation to do
some basic traffic enginering. Since I do not need bandwith reservation,
I have actually appreciated the simplicity of LDP. But it looks like
SPRING does pretty much the same thing, with less control plane overhead,
which is even more attractive.

I have a few questions for those who might know:

(a) How mature is SPRING, considering that the ISIS IGP it is built on is
well-established?

(b) Are there any noticeable behavioral differences between SPRING and LDP
implementations?

(c) Do we have any idea when P2MP LSPs will come along with SPRING? Will
it need to be coupled somehow with PIM?

Thanks.

I don't have answers for you Clarke, hopefully others out there will...

But, I do have a question... Does SPRING require an IGP ? And if so, is
ISIS the only IGP that SPRING will/can use?

SPRING uses IGP to piggyback label information ( things like SRGB,
Prefix-SID) which could be IS-IS or OSPF.

IS-IS :
https://tools.ietf.org/html/draft-ietf-isis-segment-routing-extensions-06
OSPF:
https://tools.ietf.org/html/draft-psenak-ospf-segment-routing-extensions-05

And in certain cases(like MSDC) BGP could be used as well ( BGP Prefix-SID
Attribute)

Resurrecting an older thread, Amos at oasis-tech had this to say about his
EVPN testing:

"On single active multi homing, when the CE is a L2 switch. When failing
the active link the switch will learn the remote destination MAC through
the standby link very quickly. However, when the active link recovers and
becomes active once again, the CE MAC table does not flush and the CE keep
sending traffic to backup port that is now blocking. Obviously this is
only applicable to uni directional traffic scenarios. On bi-directional
scenarios MAC learning works like a charm."

I am running up against this in our lab testing. It would be nice to find
some way have to EVPN trigger a topology change via MSTP to cause the CE
to flush its MAC table upon active link recovery.

Getting two different L2 topologies; e.g. EVPN and MSTP, within the same
L2 domain to sync up is a real pain.

Anyone have any solutions to this problem?

I don't remember if there is a log message but you can write some event
script that disable/enable the port when it become standby
Other vendor solve it with mvrp

and Juniper solve it with CFM and event script for interop with NSN

Hi all, any guidance for doing the sr-to-ldp mapping thing would be appreciated…

I tried to do the mapping server between spring (sr) and ldp but was unable to get it working. I configured the mapping server, and the client according to “Day One Segment Routing” doc and the other link below

I’m trying to make it work in my OSPF igp

Some of the docs only tell you how to do it in ISIS, but then tell you it’s possibly in OSPF, and may or may not tell you how.

One of the docs (I think Day One SR) tells you an isis ldp-stitching command is required but I don’t know how to do that in ospf or if it’s even required

One of the docs says to set srgb (sr global block) in isis, but again, I’m using ospf and don’t know how to do that or if it’s required or automagic

SPRING uses IGP to piggyback label information ( things like SRGB, Prefix-SID) which could be IS-IS or OSPF.

IS-IS : https://tools.ietf.org/html/draft-ietf-isis-segment-routing-extensions-06

OSPF: https://tools.ietf.org/html/draft-psenak-ospf-segment-routing-extensions-05

And in certain cases(like MSDC) BGP could be used as well ( BGP Prefix-SID Attribute)

I am working my way through _MPLS in the SDN Era_, and I really am intrigued
by what I read about SPRING.

I got burned a few years ago trying to deploy RSVP for traffic engineering
purposes, and I ran into so many serious JUNOS bugs, I had to abandon it and
use LDP to handle labels and stick with IGP metric manipulation to do some
basic traffic enginering. Since I do not need bandwith reservation, I have
actually appreciated the simplicity of LDP. But it looks like SPRING does
pretty much the same thing, with less control plane overhead, which is even
more attractive.

I have a few questions for those who might know:

(a) How mature is SPRING, considering that the ISIS IGP it is built on is
well-established?

(b) Are there any noticeable behavioral differences between SPRING and LDP
implementations?

(c) Do we have any idea when P2MP LSPs will come along with SPRING? Will it
need to be coupled somehow with PIM?

Thanks.

Hi Aaron,

LDP mapping server is not supported with OSPF yet.

Thanks,

Thanks Krzysztof, Then what is this command for "set ospf source-packet-routing mapping-server mapping-server-name..."

...And why does this document talk about LDP-SR interop using OSPF ?

SR does not require IGP you can use BGP to carry the labels.
-it's the new way of building massively scalable DCs with SR and traffic engineering.

So you say P2MP LSPs are not supported with SR yet? I haven't check so I don't know.
There will be no need for PIM.

Yes instead of label swap routers do label pop

This is not really a behavioural change. Traditionally this may occur
also, due to say FRR, or really like VPN. On ingress you'll see top
label is for you, so you pop it, then you'll do another lookup on what
remains, might be VPN label pointing to customer might be another
label pointing to another P..

Forwarding plane needs no update/change if not for lack of signalling
capabilities, P router without SR support could transit SR packets.

Yes, SR with MPLS data plane can typically be used on any device supporting MPLS today. However they may be limitations on how many labels can be pushed, and thus especially on ingress into the network there may be limitations on what can be done. Similarly for load balancing there may be a limit on the depth of the label stack a device can traverse in order to find entropy labels or the IP payload used for load balancing decisions.

SR can also use IPv6 and build stacks of IPv6 headers so not just MPLS
label stacks (a-la service chaining).

Also this is working more or less in IOS-XR (ASR9000). I've build a
basic working topology on Cisco VIRL and it worked. Haven't any
"proper" testing though as I've had no time of late.

I don't know any Juniper kit that's running SR at present.

Hi Aaron,

This is the test scenario I built.

https://null.53bits.co.uk/index.php?page=isis-basic-multi-topology

It was a about 6 months ago and I've been absolutely flat out this
year. I was planning to get the latest vMX version to see if anything
was in there and get back to exploring SR with XRv and vMX but I
haven’t had any time. I haven’t even checked what the state of SR on
Junos is. Failing that I’ll have to use the $dayjob lab if it needs
hardware support.

If SR is in any Junos version and you managed to test anything, please
post back to the list :)

Cheers,
James.

Yes, as Nick mentioned we have released several SPRING features (in
15.1F5). Some of the highlights include:

Adjacency Segments for IPv4 and IPv6
Link protection of adjacency segment using LFA/Remote LFA

Node Segments for IPv4 and IPv6
Link or node protection of node segment using LFA/Remote LFA

Tunnelling Node-Label traffic over RSVP LSP

LFA/Remote LFA for LDP traffic, using SPRING node labels for the
protection path (to eliminate need for targeted LDP session between PLR and
PQ-node)

Also in 13.3 we released sub-50ms egress PE protection using SPRING
context label (see
https://forums.juniper.net/t5/Industry-Solutions-and-Trends/Sub-50ms-PE-pro
tection-using-IGP-labels-SPRING/bc-p/262825 for more details)

At the MPLS World Congress last month, we had demos of the NorthStar
Controller doing path computation and installation of SPRING LSPs using
PCEP. (More details at
