When R1 sees a packet from S to G on the LAN that it didn't forward
there, yes, it sends an Assert.  Since it has an (S,G)RPT entry, it
sends an Assert with the RPT bit set.  R2 will reply with its better

Bill,
Don't we have to compare the metric preference first before we compare
the metrics. Since R1 has a RPT bit set in the metric preference for
the assert message it advertises - so R1 should be the winner.

Data from the source falls all the way to the receiver on DVMRP router (R2). Now the receiver on DVMRP router (R2) goes away. We send a prune all the way upstream towards the source. Now we keep the prune entry on DVMRP router (R2) for DVMRP prune lifetime and all routers in the PIM domain have a (S,G) prune entry which will expire in a while (say 210 seconds). Now we don't have an (S,G) prune entry at the MBR. If the receiver in the DVMRP domain (say DVMRP router R1) comes back then how do we receive packets from the source - if for during this duration the packets are going from source to RP during all this while. - Should (S,G) prune entry on RP be refreshed with a (*,*,RP) join from the MBR.

I have a couple of questions regarding PIM-DVMRP interop


Dvmrp(R1) ---- DVMRP(R2)----MBR(R3)----PIM(R4)----RP(R5)---PIM(R6) --- (Source)


Let's us say that the receiver is connected to the DVMRP router (R2). Data
from the source falls all the way to the receiver on DVMRP router (R2).
Now the receiver on DVMRP router (R2) goes away. We send a prune all the
way upstream towards the source. Now we keep the prune entry on DVMRP
router (R2) for DVMRP prune lifetime and all routers in the PIM domain have
a (S,G) prune entry which will expire in a while (say 210 seconds). Now we don't
have an (S,G) prune entry at the MBR. If the receiver in the DVMRP domain (say
DVMRP router R1) comes back then how do we receive packets from the source -
if for during this duration the packets are going from source to RP during
all this while.

- Should (S,G) prune entry on RP be refreshed with a (*,*,RP) join from the
MBR. If that happens data will be flowing all the way between RP and MBR
every time a (*,*,RP) join is received by RP.

- Or should (S,G) prune entries be maintained all the way between MBR and RP
so that the (S,G) join can be initiated. In this case when do we delete
the (S,G) prune entry on all routers between MBR and RP. In this case if the
receiver comes on DVMRP router R1 when we are in the pruned state then how we
do receive traffic on DVMRP router R1 since DVMRP router r1 does not have any
state information about (S,G) entry.

- Also what is the significance of (*,*,RP) prune message and when do we send
(*,*,RP) prune.

Thanks.

PIM-SM certainly works under KAME's IPv6 implementation, which is open. Have run it here happily with IPv6 vic/rat tools and our own multicast audio applications, and I understand it's on by default on the WIDE network. There's a PIM implementation ongoing for inclusion in Zebra, if IPv4 is your thing ;-) tim From owner-pim@catarina.usc.edu Sun Nov 19 23:08:10 2000 Received: from catarina.usc.edu (catarina.usc.edu [128.125.51.47]) by ietf.org (8.9.1a/8.9.1a) with SMTP id XAA16927 for ; Sun, 19 Nov 2000 23:08:09 -0500 (EST) Received: (from majordom@localhost) by catarina.usc.edu (8.9.3/8.9.3) id TAA40003 for pim-list; Sun, 19 Nov 2000 19:36:22 -0800 (PST) X-Authentication-Warning: catarina.usc.edu: majordom set sender to owner-pim@catarina.usc.edu using -f Received: from usc.edu (root@usc.edu [128.125.253.136]) by catarina.usc.edu (8.9.3/8.9.3) with ESMTP id TAA39997; Sun, 19 Nov 2000 19:36:20 -0800 (PST) Received: from smtp.263.net ([202.96.44.20]) by usc.edu (8.9.3.1/8.9.3/usc) with ESMTP id TAA00924; Sun, 19 Nov 2000 19:36:14 -0800 (PST) Received: from hjq (unknown [202.110.137.200]) by smtp.263.net (Postfix) with SMTP id E30D0205DC; Mon, 20 Nov 2000 11:34:53 +0800 (CST) Message-ID: <006e01c052a1$a10251f0$1e5aa8c0@Combrio> From: "NewComer" To: "Pavlin Ivanov Radoslavov" Cc: References: <200011200250.SAA31954@rumi.usc.edu> Subject: Re: IPTV is a Multicast-based VOD tool Date: Mon, 20 Nov 2000 11:26:01 +0800 MIME-Version: 1.0 Content-Type: text/plain; charset="Windows-1252" X-Priority: 3 X-MSMail-Priority: Normal X-Mailer: Microsoft Outlook Express 5.00.2919.6600 X-MimeOLE: Produced By Microsoft MimeOLE V5.00.2919.6600 Content-Transfer-Encoding: 8bit X-MIME-Autoconverted: from base64 to 8bit by catarina.usc.edu id TAA39998 Sender: owner-pim@catarina.usc.edu Precedence: bulk Content-Transfer-Encoding: 8bit > The right thing to summarize the above is to say > "pimd doesn't work under Linux", because for tools like MGEN there > is no need for any explicit support :) > > What version of the Linux kernel do you use?

I confirm i enabled PIMv2.(if not, the compiling could not succeed) I tried stand-alone version of pimdd for DM (http://antc.uoregon.edu/GATED/)on linux. The big problem was that it could not be compiled successfully. It prompted that it need some "include" files for LINUX. The current thing is that I can't choose the version of PIMD related to GateD5.0. We can't get the GateD5.0.

This draft is a work item of the Protocol Independent Multicast Working Group of the IETF. Title : State Refresh in PIM-DM Author(s) : D. Farinacci, I. Kouvelas, K. Windisch Filename : draft-ietf-pim-refresh-02.txt Pages : 10 Date : 28-Nov-00 This proposal extends the PIM-DM [1] protocol specification by intro- ducing the PIM State-Refresh control message. When an (S,G) entry is created in a router for a directly connected source, if the interface directly connected to the source is the incoming interface for the entry, a new timer is started: the State- Refresh-Timer [SRT(S,G)]. The State-Refresh-Timer controls periodic transmission of the PIM State-Refresh message, which is propagated hop-by-hop down the (S,G) RPF tree. When received by a router on the RPF interface, the State-Refresh message causes existing prune state to be refreshed. Addition of this heartbeat message solves many of the current prob- lems with PIM-DM. It prevents the periodic timeout of prune state in routers, greatly reducing the re-flooding of multicast traffic down the pruned branches that expire periodically. It also causes topology changes to be realised quicker than the traditional 3 minute timeout.

Basically your question on the role of the DR is valid if you don't have any downstream router. If there is a downstream router, that router can send a join/prune toward its RPF neighbor which could be different from that of the DR, so assert could happen when data comes down both the RPF router and the DR router. --Billy > -----Original Message----- > From: Vinodkumar Parasmal [mailto:vinodkumar.paras@wipro.com] > Sent: Thursday, November 30, 2000 5:33 AM > To: IDMR > Subject: Assert messages in PIM-SM > > > Hi all, > I have a doubt regarding PIM-SM Assert and DR Mechanisms in > multi-access > LANs.I could not justify why we need Assert when we have a DR Election > mechanism and a DR Elected thro' that mechanism.According to my > understanding the DR will be responsible for sending all PIM > control packets > and forwarding Multicast Data . > Could somebody point out the different scenarios which > explain the need for > both the mechanisms . > > Thanks in Advance > Vinod > > > > From owner-pim@catarina.usc.edu Thu Nov 30 10:20:45 2000 Received: from catarina.usc.edu (catarina.usc.edu [128.125.51.47]) by ietf.org (8.9.1a/8.9.1a) with SMTP id KAA18414 for ; Thu, 30 Nov 2000 10:20:44 -0500 (EST) Received: (from majordom@localhost) by catarina.usc.edu (8.9.3/8.9.3) id GAA92462 for pim-list; Thu, 30 Nov 2000 06:48:45 -0800 (PST) X-Authentication-Warning: catarina.usc.edu: majordom set sender to owner-pim@catarina.usc.edu using -f Received: from usc.edu (root@usc.edu [128.125.253.136]) by catarina.usc.edu (8.9.3/8.9.3) with ESMTP id GAA92457 for ; Thu, 30 Nov 2000 06:48:44 -0800 (PST) From: V@tzw.de Received: from mail2.cpip.net.cn ([210.73.64.199]) by usc.edu (8.9.3.1/8.9.3/usc) with ESMTP id GAA18413 for ; Thu, 30 Nov 2000 06:48:43 -0800 (PST) Date: Thu, 30 Nov 2000 06:48:43 -0800 (PST) Message-Id: <200011301448.GAA18413@usc.edu> Received: from h809 ([63.30.200.103]) by mail2.cpip.net.cn (Netscape Messaging Server 3.01) with SMTP id ADW19652; Thu, 30 Nov 2000 22:45:00 +0800 To: V@tzw.de Subject: Lady V: The Pleasure Pill for Women!

Hi,
I have the following question on assert behaviour on = a multi access lan.
Consider the scenario:

        =         Src
        =         |
           = R1 (RP)
        =         |
        --------------
        R2      =         R3
        |       =          |
        --------------
               |
        --------------------------
        |       =          = |      =         |
        R4      =         = R5      =         R6
        |       =         = |       =         |
        Rcv1    =         Rcv2    =         Rcv3

R1- RP and also connected to Src, Receivers connected = to R4, R5
R4 picks R2 as upstream and R5/R6 pick R3 as = upstream to Src/RP
R2 is elected as the assert winner on multiaccess = LAN for forwarding pkts from Src.
When receivers(Rcv1 & Rcv2) connected to R4 and = R5 leave, R2 prunes off the interface.
When a new receiver(Rcv3) comes up on R6 , we = initiate a (*G) join to R3. But R3 is the assert loser and an asserted = vif has higher precendence over a joined vif. How do packets get routed = to Rcvr3?

Thanks,

How do packets get routed to Rcvr3? Referring to figure 11 in section 4.5.2 of draft-ietf-pim-v2-new-01.ps, (or the table below it if you're looking at the .txt version), receiving a (*,G) Join moves the router from "I am Assert Loser" state to "No Info" state, allowing the interface to be placed back in the computed interface list and then causing the Assert process to reoccur if necessary. RFC2362 section 3.2.2/join/1/2 also says that when you get a (*,G) join you immediately add the interface.

What if >the local [Hello-Holdtime] is different from the neighbor's? Then your subnet is misconfigured and may not work properly. PIM routers should include the Holdtime option in Hellos when their Hello_Period is different than the default in the spec, in order to prevent such misconfigurations. >Is it mandatory that Hello packets carry the Holdtime? Not if it is the default. >Do PIM implementations ignore Hello packets with no Holdtime? Good question; this is a place to check compatability between old spec and new (since the old spec says you copy the hold time from the option and doesn't say what to do if it's not there). Bill
