Re: Last Call: draft-ietf-mpls-tp-data-plane (MPLS Transport Profile Data Plane Architecture) to Proposed Standard


hi,all editors
About section 3.2 , there is the following paragraph:
"   If the section is an LSP, this information MAY be implied by
  the LSP label or, if the LSP payload is MPLS-labeled, by the setting
  of the S bit.  Additional labels MAY also be used if necessary to
  distinguish different payload types"
IMO, if the client traffic of section layer is MPLS-labeled, the S bit of
section label must be set 1.
if my understanding is true, maybe violate MPLS-TP framework?
in my memory,only S bit of the lowest label should be set 1 in MPLS Label stack,
there can be only one S-bit set in a label stack.

maybe i  misunderstand the sentence? I hope it can clarify this paragragh clearly.

best regards
liu

joint ccamp and mpls working group last call on draft-ietf-mpls-explicit-resource-control-bundle+07


All,

in mid-February the draft-ietf-mpls-explicit-resource-control-bundle
was retruned to the MPLS Working Group from the responsible AD
stating that:

- it had been a long time since the working group last call
- the version that were working group last called was much earlier
   than the one we requested publication for, i.e. the document has
   changed many times since the wg last call
- this document is also of interest for the CCAMP working group, and
   the working group last call should have been jointly between MPLS
   and CCAMP
- there is a need to poll both working group to see if there is
   an interest in this draft.

However it also needs to pointed out that there are at least two deployed
implementations and we need to amke the reservation of the code points
in the IANA section.

This is to start a joint CCAMP and MPLS working group last call on
draft-ietf-mpls-explicit-resource-control-bundle-07.

Please send your comments to the mpls and ccamp working group list.

The joint working group last call ends eob June 16.

Re: Last Calls on P2MP LSP Ping and Enhanced DS Map

Hi Shiv, Nitin,

I will updated the P2MP OAM draft to reflect the PHP scenario. 

So does PHP always happen before bud node? Consider the following
topology:

  H - M1 - B - M2 - T

Here:
 H: Head
 M1, M2: Two mid-point nodes
 B: Bud
 T: Tail

So will both M1 and M2 send out unlabelled packets? Will the TTL of the
packet cause any different behavior from M1 and M2?

Also, your suggestion applies to only packets with T bit turned on,
correct? If it is for all ping/trace packets, then I foresee some
issues, where certain nodes will never respond.

Thanks,
Shaleen

Re: Last Calls on P2MP LSP Ping and Enhanced DS Map

Hi shaleen,

I have one more suggestion

Section:
3.2.1. Egress Address P2MP Responder Identifier Sub-TLVs
"A node that receives an echo request with this Sub-TLV present MUST
   respond only if the node lies on the path to the address in the
   Sub-TLV."

The above statement hold goods only in case of traceroute mode of LSP
ping.

if we want to do a normal p2mp ping (just consider pinging a single p2mp
egress), and apply the above rule we'll end up in a wrong scenario.

consider:

         ttl-1        ttl-2       ttl-3      ttl-4      ttl-5
         Bud node    Bud node    Bud node    Bud node Pure-egress
A-----------B-----------C-----------D-----------E----------F
|-----------| lsp1
|-----------------------| lsp2
|-----------------------------------| lsp3
|-----------------------------------------------| lsp4
|----------------------------------------------------------| lsp5

The ping request sent from A will reach all the egress (including bud
nodes)
So as per the section 3.2.1 all the bud nodes are on the path to egress
and everybody will respond.

so i guess 3.2.1 section can be improved by mentioning that the rule is
applicable in case of traceroute mode of ping only and for normal ping
scenario a node must reply only if it the actual egress.

finding if a ping packets is for trace or not can be decided
1) examining if any down map tlvs are there.
2) may be add one more flag saying ++traceroute mode++ of LSP ping is
being done.

option 2 seems a cleaner way of handling this. As we may also need some
way of knowing , if the packet is for trace mode/ ping mode for some
other cases also.

in any case section 3.2.1 needs this updation.

...$hiv

Re: Last Calls on P2MP LSP Ping and Enhanced DS Map

|I will updated the P2MP OAM draft to reflect the PHP scenario.

|So does PHP always happen before bud node? Consider the following
|topology:

|  H - M1 - B - M2 - T
|
|Here:
| H: Head
| M1, M2: Two mid-point nodes

| T: Tail

PHP will happen before tail (T i.e pure egress) also.
In the example T is pure egress, so packet should be processed by T, but
in case of B (bud node) it should be dropped.

That's why it should be clearly specified as 

"In p2mp LSP case, if a node (other than ++pure egress++) receives a
+MPLS
LSP trace packet+, without any label, then it should drop the packet
without processing"

In other words, "if a bud node receives a unlabelled packets , then it
should be dropped"

|
|So will both M1 and M2 send out unlabelled packets? Will the TTL of the
|packet cause any different behavior from M1 and M2?

I guess, there should not be any problems as such.

|Also, your suggestion applies to only packets with T bit turned on,
|correct? If it is for all ping/trace packets, then I foresee some
|issues, where certain nodes will never respond.

That's correct. The packets should be dropped only if T bit is set.
Other wise in ping mode of operation, we may not get reply at all if we
apply this rule to all packets.

  Nothing worth noting in the WG process. Good consensus.

Document Quality

  This is an informational framework.
  The Document is now widely referenced by other documents.
  The document has been well reviewed in the MPLS and CCAMP WGs.
  It has also received a substantial (earlyish) SecDir review and
  been updated
  The document was gen-Art reviewed.

Re: Last Calls on P2MP LSP Ping and Enhanced DS Map

Hi,

Can you do ping with Node Address P2MP Responder Identifier instead of
Egress Address P2MP Responder Identifier? Then no other node would
respond.

Re: LDP Discovery

Somasundaram,

One area of discussion that is not allowed on this mailing list is discussion
of why a particular vendor does or does not do something in the way that
the standard(s) define(s).

Please address that part of this question to appropriate product support.

As for the rest of the question, it is not always possible to address issues
with misconfiguration in protocol specification and - unless a particular
misconfiguration is likely to produce drastic pathological behavior in a
network - it is usually not worth the trouble to try to identify all of the
(probably very many) ways that devices may be misconfigured.  In my
experience, this is particularly true when the major effect of such an
error in configuration is to embarras the vendor(s) that allowed it in
the first place.

Subject: [mpls] LDP Discovery

     I have a question on LDP Basic Discovery Process.
Hi All,

        Am looking out for some clarification on LDP Discovery process.

        LDP Hellos are sent to All routers Multicast Address (224.0.0.2).So any LDP capable router on recieveing
this packet reaches Full neighborship.

          I had a strange (infact a misconfiguration) setup, wherein I had address configured incorrectly. For
example, address on a different subnet over the directly connected
interfaces.(1.1.1.1/24<http://1.1.1.1/24> <----> 1.1.2.1/24<http://1.1.2.1/24>)

        I could still see the adjacency coming up. In other words, we are not doing a source-address check.I went
through some juniper documentation on LDP and understood that they have a knob (CLI) to enable/disable source-address.

        I am just curious to understand why was the source-address check not mentioned in the RFC.

        Is it fine that the neighborship gets established inspite of having a misconfiguration? If the answer to
the question is yes, can you share your thoughts on why Juniper could have included the source-address check?

Regards
Somasundaram
