Last updated: 8 April 1994


This README is for IRIX 5.1 and 5.2 users.

This directory contains updates for multicast routing on IRIX 5.1 and 5.2.
The mrouted binary is version 2.2 from Van Jacobson et al, which has 
his 8 April 1994 routing update fixes.  These changes are important 
if you're connected to the MBONE. Even better, upgrade to IRIX 5.3
and get the latest mrouted 3.8 from ../5.3.

See ../../README.tools for information on the various MBONE conferencing tools.


*** WARNINGS ***
a) This is an unofficial, unsupported release. 
b) The binaries should work on IRIX 5.1 but there's no guarantees since 
   they were compiled on 5.2.

If you have any problems with these fixes, please let me know via email.

1) mrouted(1M) changes for IRIX 5.2:

    *** These changes have received minimal testing. Be sure to save a backup 
    *** mrouted.

    Here are binaries and sources for Van Jacobson and Pavel Curtis's version
    of mrouted(1M) with their extensions to obtain mrouted's neighbor list
    and Van's changes to make router updates more robust.
    Some of the source files contain the small changes needed to run on IRIX. 
    The original sources were obtained via anonymous ftp from 
    ftp.ee.lbl.gov:/mrouted-2.2/mrouted.tar.Z on 8 April 1994.

    Binaries:
	<fetch mrouted.Z in binary mode>
	uncompress mrouted.Z

    Sources: (optional)
	<fetch mrouted-2.2-src.tar.Z in binary mode>
	zcat mrouted-src.tar.Z | tar xf -
	cd mrouted
	make

    To install, as root:
	mv /usr/etc/mrouted /usr/etc/SAVE.mrouted
	mv mrouted /usr/etc
	killall mrouted
	mrouted


2) Useful tools for IRIX 5.2:

    Van's mrinfo program is used to query a mrouted for its neighbor list.
    Pavel's map-mbone is used to query all reachable mrouteds for their lists.

    Binaries:
	<fetch map-mbone.Z and mrinfo.Z in binary mode>
	uncompress map-mbone.Z mrinfo.Z

    Sources: (optional)
	<fetch mrouted-2.2-src.tar.Z in binary mode>
	zcat mrouted-src.tar.Z | tar xf -
	cd mrouted
	make

    To install, as root:
	mv mrinfo map-mbone /usr/etc
