Garry, There is quite a bit of info and some sample configs for MPLS over GRE: Juniper: MPLS LSPs can use GRE tunnels to cross routing areas, Autonomous Systems, and ISPs. Bridging MPLS LSPs over an intervening IP domain is possible without disrupting the outlying MPLS domain. LSPs can reach any destination that the GRE tunnels can reach. MPLS applications can be deployed without requiring all transit nodes to support MPLS, or requiring all transit nodes to support the same label distribution protocols (LDP or RSVP). If you use CSPF, you must configure OSPF or IS-IS through the GRE tunnel. Traffic engineering is not supported over GRE tunnels; for example, you cannot reserve bandwidth or set priority or preemption. For more information about GRE tunnels, see the JUNOS Internet Software Configuration Guide: Interfaces and Class of Service. http://www.juniper.net/techpubs/software/junos/junos53/swconfig53-mpls-apps/ html/mpls-signaled-config45.html http://www.juniper.net/techpubs/software/junos/junos53/swconfig53-mpls-apps/ html/mpls-signaled-config46.html Also various articles, whitepapers: http://www.nanog.org/mtg-0402/pdf/townsley.pdf http://www1.ietf.org/proceedings_new/04nov/slides/mpls-8/mpls8.ppt http://www.watersprings.org/pub/id/draft-rekhter-mpls-over-gre-03.txt http://www.cisco.com/en/US/about/ac123/ac114/ac173/Q1-05/tech_security.html A search of the vendor sites (Cisco, Juniper, Riverstone etc) produces quite a bit of info + IETF, NANOG, MPLSRC, MPLS & Frame-relay Alliance etc http://www.ietf.org/internet-drafts/draft-ietf-l3vpn-gre-ip-2547-03.txt Doug -----Original Message----- From: mpls-ops-request@mplsrc.com [mailto:mpls-ops-request@mplsrc.com] On Behalf Of Garry Glendown Sent: 19 April 2005 08:06 To: mpls-ops@mplsrc.com Subject: [MPLS-OPS]: Tunneling MPLS over non-MPLS network Hi, I was wondering if there is a way to tunnel MPLS traffic over a non-MPLS link? Hardware is Cisco routers, and link would have to account for an MTU for 1500 or possibly less ... Any idea?
