++QUAGGA PLUGIN FOR OLSRD
++by Immo 'FaUl' Wehrenberg <immo@chaostreff-dortmund.de>
++---------------------------------------------------------------------
++
++This is the Quagga Plugin for the OLSRD.
++It allowes olsrd to redistribute from various quagga-protocols
++as well as to export olsr-routes to quagga so that they can be
++redistributed by the quagga-routing-daemons.
++
++Note Sven-Ola: You also need a source distribution of quagga-0.98.5
++or quagga-0.98.6 (that is the current stable). The quagga source tree
++needs to be patched with quagga-0.98.6-olsr.diff, compiled and installed
++via 'make install'. Because many people will otherwise have compile
++probs, I've added 2 include files in lib/quagga/src/quagga. If you
++want to use another version of quagga, make sure to remove these
++before you compile the olsrd_quagga plugin.
++
++---------------------------------------------------------------------
++PLUGIN PARAMETERS (PlParam)
++---------------------------------------------------------------------
++
++PlParam "redistribute" "<protocol>"
++ where protocol is one of the following:
++ system, kernel, connect, static, rip, ripng, ospf, ospf6,
++ isis, bgp, hsls
++ May be used more then once
++
++PlParam "ExportRoutes" "<only/both>"
++ exportes olsr-routes to quagga or to both, quagga and kernel
++ no routes are exportet if not set.
++
++PlParam "Localpref" "true"
++ sets the zebra SELECTED-flag on the routes exported to zebra
++ which means these routes are prefered in any case.
++
++PlParam "Distance" "0-255"
++ allowes to set Administrative distance to routes exported
++ to zebra.
++
++---------------------------------------------------------------------
++SAMPLE CONFIG
++---------------------------------------------------------------------
++
++add in /etc/olsrd.conf:
++
++LoadPlugin "olsrd_quagga.so.0.2.2"
++{
++ PlParam "redistribute" "ospf"
++ PlParam "redistribute" "bgp"
++ PlParam "ExportRoutes" "only"
++ PlParam "Distance" "125"
++ PlParam "Localpref" "false"
++}

++BASIC MULTICAST FORWARDING PLUGIN FOR OLSRD
++by Erik Tromp (erik.tromp@nl.thalesgroup.com)
++
++12 Jul 2006: Version 1.1
++* Major updates in code forwarding from and to non-OLSR enabled
++ network interfaces.
++* Debug level 9 gives a better indication of what happens to each
++ handled multicast/broadcast packet.
++* Can now deal with network interface removal ("ifdown eth1") and
++ addition ("ifup eth1").
++* CRC-calculation for duplicate detection is done over first 256
++ bytes in packet instead of over full packet length.
++* CRC calculated only on captured packets, and is subsequently
++ passed on in a special OLSR-BMF encapsulation header.
++* Deals correctly with fragmented packets
++
++27 Apr 2006: Version 1.0.1
++* First release.
++
++1. Introduction
++---------------
++
++The Basic Multicast Forwarding Plugin floods IP-multicast and
++IP-local-broadcast traffic over an OLSRD network. It uses the
++Multi-Point Relays (MPRs) as identified by the OLSR protocol
++to optimize the flooding of multicast and local broadcast packets
++to all the nodes in the network. To prevent broadcast storms, a
++history of packets is kept; only packets that have not been seen
++in the past 3-6 seconds are forwarded.
++
++In the IP header there is room for only two IP-addresses:
++* the destination IP address (in our case either a multicast
++ IP-address 224.0.0.0...239.255.255.255, or a local broadcast
++ address e.g. 192.168.1.255), and
++* the source IP address (the originator).
++
++For optimized flooding, however, we need more information. Let's
++assume we are the BMF process on one node. We will need to know which
++node forwarded the IP packet to us. Since OLSR keeps track of which
++nodes select our node as MPR (see the olsr_lookup_mprs_set function),
++we can determine if the node that forwarded the packet, has selected us as
++MPR. If so, we must also forward the packet, changing the 'forwarded-by'
++IP-address to that of us.
++
++Because we need more information than fits in a normal IP-header, the
++original packets are encapsulated into a new IP packet. Encapsulated
++packets are transported in UDP, port 50505. The source address of the
++encapsulation packet is set to the address of the forwarder instead of
++the originator. Of course, the payload of the encapsulation packet is
++the original IP packet.
++
++For local reception, each received encapsulated packets is unpacked
++and passed into a tuntap interface which is specially created for
++this purpose.
++
++Here is in short how the flooding works (see also the
++BmfEncapsulatedPacketReceived(...) function; details with respect to
++the forwarding towards non-OLSR enabled nodes are omitted):
++
++ On all OLSR-enabled interfaces, setup reception of packets
++ on UDP port 50505.
++ Upon reception of such a packet:
++ If the received packet was sent by myself, drop it.
++ If the packet was recently seen, drop it.
++ Unpack the encapsulated packet and send a copy to myself via the
++ TunTap device.
++ If I am an MPR for the node that forwarded the packet to me,
++ forward the packet to all OLSR-enabled interfaces *including*
++ the interface on which it was received.
++
++As with all good things in life, it's so simple you could have
++thought of it yourself.
++
++
++2. How to build and install
++---------------------------
++
++Follow the instructions in the base directory README file under
++section II. - BUILDING AND RUNNING OLSRD. To be sure to install
++the BMF plugin, cd to the base directory and issue the follwing
++command at the shell prompt:
++
++ make install_all
++
++Next, turn on the possibility to create a tuntap device (see also
++/usr/src/linux/Documentation/networking/tuntap.txt)
++
++ mkdir /dev/net # if it doesn't exist already
++ mknod /dev/net/tun c 10 200
++
++Set permissions, e.g.:
++ chmod 0700 /dev/net/tun
++
++Edit the file /etc/olsrd.conf to load the BMF plugin. For example:
++
++ LoadPlugin "olsrd_bmf.so.1.1"
++ {
++ # No PlParam entries required for basic operation
++ }
++
++
++3. How to run
++-------------
++
++After building and installing OLSRD with the BMF plugin, run the
++olsrd deamon by entering at the shell prompt:
++ olsrd
++
++Look at the output; it should list the BMF plugin, e.g.:
++
++ ---------- Plugin loader ----------
++ Library: olsrd_bmf.so.1.1
++ OLSRD Basic Multicast Forwarding plugin 1.1 (Jul 12 2006 04:12:42)
++ (C) Thales Communications Huizen, Netherlands
++ Erik Tromp (erik.tromp@nl.thalesgroup.com)
++ Checking plugin interface version... 4 - OK
++ Trying to fetch plugin init function... OK
++ Trying to fetch param function... OK
++ Sending parameters...
++ "NonOlsrIf"/"eth0"... OK
++ Running plugin_init function...
++ OLSRD Basic Multicast Forwarding plugin: opened 6 sockets
++ ---------- LIBRARY LOADED ----------
++
++
++4. How to check if it works
++---------------------------
++
++To check that BMF is working, enter the following command on the
++command prompt:
++
++ ping -I eth1 224.0.0.1
++
++Replace eth1 with the name of any OLSR-enabled network interface.
++
++All OLSR-BMF nodes in the MANET should respond. For example:
++
++root@IsdbServer:~# ping -I eth1 224.0.0.1
++PING 224.0.0.1 (224.0.0.1) from 192.168.151.50 eth1: 56(84) bytes of data.
++64 bytes from 192.168.151.50: icmp_seq=1 ttl=64 time=0.511 ms
++64 bytes from 192.168.151.53: icmp_seq=1 ttl=64 time=4.67 ms (DUP!)
++64 bytes from 192.168.151.55: icmp_seq=1 ttl=63 time=10.7 ms (DUP!)
++64 bytes from 192.168.151.50: icmp_seq=2 ttl=64 time=0.076 ms

++64 bytes from 192.168.151.55: icmp_seq=3 ttl=63 time=5.62 ms (DUP!)
++64 bytes from 192.168.151.50: icmp_seq=4 ttl=64 time=0.158 ms
++64 bytes from 192.168.151.53: icmp_seq=4 ttl=64 time=1.14 ms (DUP!)
++64 bytes from 192.168.151.55: icmp_seq=4 ttl=63 time=1.16 ms (DUP!)
++
++
++5. Adding non-OLSR interfaces to the multicast flooding
++-------------------------------------------------------
++
++As a special feature, it is possible to have multicast and local-broadcast
++IP packets forwarded also on non-OLSR interfaces.
++
++If you have network interfaces on which OLSR is *not* running, but you *do*
++want to forward multicast and local-broadcast IP packets, specify these
++interfaces one by one as "NonOlsrIf" parameters in the BMF plugin section
++of /etc/olsrd.conf. For example:
++
++ LoadPlugin "olsrd_bmf.so.1.1"
++ {
++ # Non-OLSR interfaces to participate in the multicast flooding
++ PlParam "NonOlsrIf" "eth2"
++ PlParam "NonOlsrIf" "eth3"
++ }
++
++If an interface is listed both as NonOlsrIf for BMF, and in the
++Interfaces { ... } section of olsrd.conf, it will be seen by BMF
++as an OLSR-enabled interface.
++
++Note that when BMF receives or sends a packet via a non-OLSR interface,
++the TTL is decremented. TTL is NOT decremented on packets traveling
++within the OLSR-BMF MANET, since that is considered to be one (repaired)
++broadcast domain.
++
++Packets are not forwarded from one non-OLSR interface to another non-OLSR
++interface, only from non-OLSR interfaces to OLSR interfaces and vice versa.
++Packet forwarding between non-OLSR interfaces should be the result of
++other multicast routing protocols.
++
++
++6. Testing in a lab environment
++-------------------------------
++
++Setup IP-tables to drop packets from nodes which are not
++direct (1-hop) neigbors. For example, to drop all packets from
++a host with MAC address 00:0C:29:28:0E:CC, enter at the shell prompt:
++
++ iptables -A INPUT -m mac --mac-source 00:0C:29:28:0E:CC -j DROP
++
++Edit the file /etc/olsrd.conf, and specify the MAC addresses of the nodes
++we do not want to see; even though packets from these nodes are dropped
++by iptables, they are still received on network interfaces which are in
++promiscuous mode. For example:
++
++ LoadPlugin "olsrd_bmf.so.1.1"
++ {
++ # Drop all packets received from the following MAC sources
++ PlParam "DropMac" "00:0C:29:C6:E2:61" # RemoteClient1
++ PlParam "DropMac" "00:0C:29:61:34:B7" # SimpleClient1
++ PlParam "DropMac" "00:0C:29:28:0E:CC" # SimpleClient2
++ }
++
++
++
++7. Common problems, FAQ
++-----------------------
++
++Question:
++On which platforms does BMF currently compile?
++
++Answer:
++Only on Linux. No compilation on Windows (yet). The oldest Linux
++kernel on which the BMF plugin was tested was version 2.4.18.
++
++
++Question:
++When starting OLSRD with the BMF plugin, I can see the following
++error message:
++
++OLSRD Basic Multicast Forwarding plugin: error opening /dev/net/tun: No such file or directory
++
++Wat to do?
++
++Answer:
++Turn on the possibility to create a tuntap device; see section 2 of this
++file.
