I have read through the archives as far back as Dec 2005, and have found an number of related postings, but nothing that has helped me so far. I have tried various configuration settings, and am currently using the config suggested by Pavlin a few months ago: http://mailman.icsi.berkeley.edu/pipermail/xorp-users/2006-December/001579.html Notes: The only changes I have made to the config above is: - the IP address of the statically configured RP to match my network. - enabled pimsm4 trace options with 'set protocols pimsm4 traceoptions flag all disable false' The group address for all tests is 225.1.1.2 Between each test, I issued "clear ip mroute 225.1.1.2" on the cisco router. I've substituted the words TestA, TestB etc in some of the output below in place of the specific IP addresses involved In all tests, I have verified I can ping back and forth between the test machines. In all tests, 'show pim mrib' shows the unicast routes, as expected. Scenario 1: TestA(LISTENING) --[switch1]--- CiscoRtr(RP) ---[switch2] ---- eth0:xorp:eth1 ----[switch3]--- TestB(SENDING) - Cisco router shows an ip mroute for (*,225.1.1.2), with no incoming interfaces, and one outgoing interface (to TestA) - xorp pimsm4 trace output shows it receives and sends lots of PIM_HELLO messages, and it sees the cisco as a neighbour (show pim nei) - The output of 'show pim join' does NOT show anything about 225.1.1.2, but does show the expected 224 groups that xorp is a member of - the output of 'show igmp group' does NOT show anything about 225.1.1.2, but does show all the 224 groups (as above) - Client TestA sees nothing Scenario 2: TestA(SENDING) --[switch1]--- CiscoRtr(RP) ---[switch2] ---- eth0:xorp:eth1 ----[switch3]--- TestB(LISTENING) - Cisco router shows ip mroute entry for (*,225.1.1.2), incoming null, outgoing null - Cisco router shows ip mroute entry for (TestA, 225.1.1.2), incoming TestA_Subnet, outgoing null - Xorp 'show igmp groups' shows "eth1 225.1.1.2 0.0.0.0 TestB 223 2 E" - Xorp 'show pim mfc' shows 224.0.1.39, 224.0.1.40, but NOT 225.1.1.2 - Xorp 'show pim join' shows an entry for 225.1.1.2, with upstream state on eth0 'NotJoined' - I think this is a problem. - Client TestB sees nothing Control Test 1: TestA(SENDING)--[switch1]--TestB(RECEIVING) - Works fine Control Test 2: TestA(SENDING)--[switch1]--CiscoRouter--[switch2]--TestB(RECEIVING) - Works fine It seems to me that although xorp picks up the IGMP information correctly when it has the client connected to it, it doesn't get that info into PIM, or at least not to the PIM neighbours.

Also, the "show pim join" command shouldn't show any (*,G) state about 225.1.1.2. Only after TestB starts sending, then the XORP router should have a (S,G) PIM-SM state that you should see by "show pim join": the incoming interface for that entry should be eth1, while the outgoing interface should be the pim_register vif. The data packets from TestB should be encapsulated inside PIM Register and unicast to the RP. If you don't see the (S,G) state, please make sure that the RP Set inside XORP is fine ("show pim rps") and the RPF information toward the RP is in place ("show pim mrib"). If they are fine, please enable the traceoptions in the MFEA and PIM-SM and look for any logs for UPCALL messages from the kernel: those messages should start appearing after TestB starts transmitting. > - Client TestA sees nothing > > Scenario 2: > TestA(SENDING) --[switch1]--- CiscoRtr(RP) ---[switch2] ---- > eth0:xorp:eth1 ----[switch3]--- TestB(LISTENING) > - Cisco router shows ip mroute entry for (*,225.1.1.2), incoming null, > outgoing null > - Cisco router shows ip mroute entry for (TestA, 225.1.1.2), incoming > TestA_Subnet, outgoing null > - Xorp 'show igmp groups' shows "eth1 225.1.1.2 > 0.0.0.0 TestB 223 2 E" The "show igmp groups" output seems fine. > - Xorp 'show pim mfc' shows 224.0.1.39, 224.0.1.40, but NOT 225.1.1.2 > - Xorp 'show pim join' shows an entry for 225.1.1.2, with upstream state > on eth0 'NotJoined' - I think this is a problem. Yes, this is a problem. Same as the previous case, please check that the "show pim rps" lists CiscoRtr as the RP, and that "show pim mrib" shows the correct RPF information toward the RP. Finally, double check that XORP indeed sees Cisco as a neighbor (and vice versa). If all this information seems fine, please send the "show pim join" output.

How can I do it and analyze it? You need a packet generator that can generate PIM Register messages fast enough. It should allow you to vary the frequency of the messages. I have heard about the following PIM packet generator, but I've never used it: http://www.pim-sm-generator.com/ You could also try Scapy which is a very powerful tool: http://www.secdev.org/projects/scapy/ Then you need to design a strategy about observing the router behavior. E.g., its CPU load, the impact on forwarding other multicast data traffic, etc. Are you planning to write a report or a paper on the subject? It will be great if you can send the URL to your work once you are done. Regards, Pavlin > Thanks, > > Rodrigo M. M.

Hi, firewalling and QoS enforcing are the functions of a packet forwarding plane, and are very much OS / platform specific. XORP as a portable routing protocol software does not (yet) provide interfaces to such OS-specific forwaring plane features, though you might wish to take a look at Vyatta OFR (www.vyatta.com), which while using XORP in its control plane also provides an integrated interface to forwarding plane functions such as NAT, firewall, VLANs etc. Hope this helps, Marko From ar_djp at yahoo.com Wed Apr 25 18:11:23 2007 From: ar_djp at yahoo.com (ar) Date: Wed, 25 Apr 2007 18:11:23 -0700 (PDT) Subject: [Xorp-users] [Xorp-hackers] Does XORP Supports Multicast Routing?

The CandRP hash function is described in RFC 4601 Section 4.7.2: Value(G,M,C(i))= (1103515245 * ((1103515245 * (G&M)+12345) XOR C(i)) + 12345) mod 2^31 where C(i) is the RP address and M is a hash-mask. ... The hash-mask allows a small number of consecutive groups (e.g., 4) to always hash to the same RP. ... For address families other than IPv4, a 32-bit digest to be used as C(i) and G must first be derived from the actual RP or group address. Such a digest method must be used consistently throughout the PIM domain. For IPv6 addresses, we recommend using the equivalent IPv4 address for an IPv4-compatible address, and the exclusive-or of each 32-bit segment of the address for all other IPv6 addresses. For example, the digest of the IPv6 address 3ffe:b00:c18:1::10 would be computed as 0x3ffe0b00 ^ 0x0c180001 ^ 0x00000000 ^ 0x00000010, where ^ represents the exclusive-or operation. 2. The candidate RP with the highest resulting hash value is then the RP chosen by this Hash Function. If more than one RP has the same highest hash value, the RP with the highest IP address is chosen. Hence, if you use hash mask length of 128 (instead of the default 126 for example), then the result should be that you can't guarantee that 4 consecutive groups will match to the same CandRP. Of course, it could be possible that the output of the hash function for the groups you have tried is such that one particular CandRP is the chosen one, but the probability for that should be low. The best thing would be to write a short test program that implements the above hash function and calculates what the RP should be. Then match the output to what Cisco and XORP think. This should tell you whether the problem is in Cisco or XORP. Regards, Pavlin From arthur at layese.com Thu Apr 26 18:50:37 2007 From: arthur at layese.com (Arthur N.
