一个可以实现MPLS实验的linux源代码.你不仅可以实现单层标签的转发,还可以实现2个标签的实验,很好的.

The prefered method of installing a MPLS enabled kernel is to use the
RPMs I have prepared.  If you run a non RPM system you will have
to compile a kernel by hand.  Here are some quick steps to help you
get going:

-get Linux kernel 2.6.15

-change directory to /usr/src
	cd /usr/src
-uncompress/untar linux-2.6.15.tar.gz
	tar -zxvf linux-2.6.15.tar.gz
-uncompress/untar mpls-linux-1.950.tgz
	tar -zxvf mpls-linux-1.950.tgz
-change directory to linux
	cd linux-2.6.15
-patch Linux kernel for MPLS for Linux
	patch -p1 < ../mpls-linux/patches/linux-kernel.diff

-configure Linux kernel to turn on MPLS (atleast the following)
	make menuconfig

Standard config:

	Code maturity level options  --->
	[*] Prompt for development and/or incomplete code/drivers
	Networking options  --->
	  [*] Multi Protocol Label Switching - MPLS

For more advanced traffic mappings (in addition to Standard config):

	[*] Network packet filtering (replaces ipchains)
	  IP: Netfilter Configuration  --->

	<*> IP tables support (required for filtering/masq/NAT)
	    <*> MPLS target support

-compile and install kernel
	make clean ; make vmlinux
	(then follow the rules for your distrubution to install the kernel)
-reboot

-build the a MPLS enhanced version of iproute2 to create MPLS segments and
 bind routes to LSPs. (read patches/README.iproute2)
-For more advanced traffic mappings you will need to use iptables
 (read patches/README.iptables)

Additional Hints
----------------
1) Make sure you know what your old kernel config was before trying to
   configure a new kernel!!!!

2) Make sure to do a 'make modules ; make modules_install' if you have
   configured any modules (you would have known that if you read
   linux/README).

3) Don't send messages to the mailing list saying:

   "I installed the mpls-linux patch and now I can't run Xwindows or
   my network doesn't work"

  These are kernel config issues, (ie not related to mpls-linux)
  Go back and read linux/README

Good luck!
