Re: [mpls-linux-general] can use mpls-linux support mpls/vpn ?

[Renato W. <ren...@gm...>]

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.
