Hi , I have installed only kernel-2.6.22.5-76.fc7.mpls.1.958.src.rpm kernel package, but I am unable to find the following option in menuconfig, please let me know if I need to install any additional packages:- * In Network Packet Filtering (replaces ipchains), IP: Netfilter configuration will be selected * In IP: Netfilter configuration menu the following minimum options will be selected [IP Netfilter Screenshot]: o <*> MPLS target support o <*> DSCP target support * In Network Packet Filering (replaces ipchains) select Bridge: Netfilter configuration * In Bridge: Netfilter configuration menu the following minimum options will be selected[Bridge Netfilter Screenshot]: o <*> ebt: MPLS target support Thanks & regards Bhartendu M. ________________________________ From: Adrian Popa [mailto:adr...@gm...] Sent: Saturday, February 02, 2008 12:08 AM To: Bhartendu Maheshwari Cc: mpl...@li... Subject: Re: [mpls-linux-general] MPLS Kernel Loading problem Hello, The part about installing the kernel sources + compiling the kernel is correct, but to actually use MPLS, you'll need at least the patched iproute package! I recommend you install iproute and iptables depending on the experiments you plan to do. The iproute package provides the mpls command which allows you to build static label paths. If you want to use LDP, you need to install quagga from the svn repository (but It might depend on the existence of the mpls command - I'm not sure - James, correct me if I'm wrong). Good luck!

Install kernel-2.6.22.5-76.fc7.mpls.1.958.src.rpm(Is this conatins kernel-devel-2.6.22.5-76.fc7.mpls.1.958.i686.rpm and kernel-headers-2.6.22.5-76.fc7.mpls.1.958.i386.rpm files??) as rpm -i kernel-2.6.22.5-76.fc7.mpls.1.958.src.rpm 2. Install kernel-devel-2.6.22.5-76.fc7.mpls.1.958.i686.rpm as rpm -i kernel-devel-2.6.22.5-76.fc7.mpls.1.958.i686.rpm 3. Install kernel-headers-2.6.22.5-76.fc7.mpls.1.958.i386.rpm as rpm -i kernel-headers-2.6.22.5-76.fc7.mpls.1.958.i386.rpm 4. Update i686 kernel file and make the changes in .config file and compile kernel 5. Install new kernel on the machine and boot with new MPLS kernel. 6. Then compile ldp-portable-0.900.tar on the machine and install it. 7. No need to install ebtables/iptables/iproute, as these changes are part of new MPLS kernel. Please confirm? Please let me know if I am missing any step or any thing is incorrect. Thanks & Regards Bhartendu M. ________________________________ From: Adrian Popa [mailto:adr...@gm...] Sent: Friday, February 01, 2008 7:55 PM To: Bhartendu Maheshwari Cc: mpl...@li... Subject: Re: [mpls-linux-general] MPLS Kernel Loading problem Hello, In order to use kernel 2.6.22 you'll have to use mpls-linux 1.9.58. You have 2 options: If you're using a fedora core system, it's much easier to install the rpms, but if you're using a different type of system (that doesn't support rpm), you'll have to patch and compile the kernel and the other tools yourself. You can follow the general steps I used here: http://www.elcom.pub.ro/~adrian.popa/mpls-linux/mpls-linux-docs/1-3-inst allation.html <http://www.elcom.pub.ro/%7Eadrian.popa/mpls-linux/mpls-linux-docs/1-3-i nstallation.html> but adjust the commands to match your version of mpls-linux and packets. The configuration options for the kernel are shown in the previous page (also with screenshots) Good luck!

Subject: Re: [mpls-linux-general] MPLS Kernel Loading problem Hello, You need to enable NFS support in the kernel (and also network drivers into the kernel), not as a module. You can enable this in File Systems -> Network File Systems -> NFS file system support (must be marked as *, not M). But... are you sure your root filesystem is mounted through NFS? I didn't think this was possible (or at least I never heard of it)... You should check the configuration for your old kernel and activate the same things in the new kernel and then activate the MPLS related options in the new kernel. Google for 'linux howto compile 2.6 kernel' for details and help (http://www.linuxforums.org/forum/linux-kernel/55612-mini-howto-compile- linux-kernel-2-6-a.html) Good luck!
