hi huang,
we've just developed a mpls network with a couple of vpn. mpls-linux can do
it...but with some trouble. the main problem is the ldp support that
unluckly it's not stable. anyway, after a careful design, you can manually
assign the label.

for further infos...mail here

Some weeks ago I've done some tests with rudimentary VPNs, without VRFs and
LDP. I have used:

   - command "network A.B.C.D/M rd ASN:nn_or_IP-address:nn tag WORD" to
   distribute vpnv4 routes
   - extcommunity-list and route-maps to deal with RTs;
   - extend bgpd daemon to automatically update the nhlfe/ilm/xc tables when
   receiving bgp_update messages

I could interact with Cisco machines (using GNS3) with no problems, but i
had to set the LSPs manually and there were no isolation (VRFs).

Also, the following RFCs are already implemented on Quagga:

   -

   RFC 2842: Capabilities Advertisement with BGP-4 Standards Track;
   -

   RFC 2858: Multiprotocol Extensions for BGP-4 Standards Track;
   -

   RFC 4360: BGP Extended Communities Attribute Standards Track;
   -

   RFC 3107: Carrying Label Information in BGP-4 Standards Track (there were
   a label codification bug on the  MP_REACH_NLRI attribute that I've
   already fixed);

Unfortunaly, adding VRF support makes things a lot harder, however i'm
working on this (extending quagga). There is still a long way to go, but
most of the job is already done.

Renato.

    Hi Renato, I have a patch to support full VRF support on zebra daemon. It is
almost agnostic about the kernel interface. Currently i have a porting layer to
a custom kernel patches I did to implement named network namespaces or current
kernels. I have to check if the quagga MPLS patches apply cleanly, they almost
did a while ago. I am now cleaning some stuff and I want to publish some code or
git tree in a week or two. At some point I had a test network with BGP feeding
the VPNV4 prefixes into my kernel, with LDP working, the only thing I needed to
have a full working VPN setup was PHP. But it was all a bit ad-hoc.

Hi Jorge and all,

I saw you were talking about a patch for linux-mpls that uses named network
namespaces, I would like to know if you are still working on the subject and
if any patches are available ?
I recently posted a (RFC) patch for the ip command that use named network
namespaces to configure net namespaces like VRFs , using Eric Biederman's
recent set of patches that allows a net namespace to get named, using the
filesystem as an "anchor point".

Please see:
https://lists.linux-foundation.org/pipermail/containers/2010-June/024699.html

(should maybe have posted to devel, but the most recent post here was
talking about this very subject so...)

Thanks,

    I still work on it, i have been using myself some patches from Vivien
Chappelier to have ID for netns's that I patched on top to have names too.

    I did the correspondig patches for ip utility too. We have been using it on our
network for some years already.

    I have a patched Quagga too with support for this infrastructure that I am
cleaning up, trying to put it in a git repository and learning git at the same
time (so it is going slowly ;).

    I already knew about Biederman's patches and wanted to take a look at using
them for Quagga as they seem to be the ones that are going to be accepted
upstream. I don't have too much time now to do research but if you can sent me
or point to the needed patches I'll add support in Quagga and publish it.

    Regards,
        Jorge
