I think I missed this in the original post and just mentioned the MPLS technologies. I know at least the ERX series supports L2TP. I have never done this on juniper equipment so I'm not much help in this respect. If I had the choice I'd implement a simple MPLS configuration though since it will allow more advanced features such as traffic engineering and mapping the circuits over specific links through admin groups or SRO/RRO (RSVP). Also, l2circuit/l2vpn is not multipoint, that is the purpose of vpls..

What if you want to use pseudo-wire services (like L2TPv3 (Cisco)) when you don?t have MPLS environment. Second if l2vpn is multipoint than what?s the usage of VPLS. Is there any significant difference between l2vpn and VPLS. Can?t you have pseudo-wire circuit on traditional IP network ( just like cisco L2TPVv3).

For example l2vpn is based on MBGP with RSVP doing the LSP signaling and advertising the labels. This means that the path of the circuit is handled as if it were a virtual circuit because RSVP signals and reserves the bandwidth before traffic is passed. l2circuit is based on LDP which sends hellos end to end but depends on the IGP for resource reservations. The data forwarding is technically the same and you can achieve the same results with either though. Personally, I'm a fan of l2vpn the use of RSVP allows for more tidy configuration and bandwidth reservations. I think l2vpn is a little easier to troubleshoot as well, however YMMV.

Which is best in replacing Cisco L2TPv3 pseudo-wr. _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
