[j-nsp] l2circuit or l2vpn

[Andrew Jimmy]

Well, this means that you need to have MPLS switching in both case either
l2ciruict or l2vpn. 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).

The main differences are related to the Martini and Kompella method of
implementing the technology. 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.

What are the major differences between l2cirucit and l2vpn in terms of
Juniper JUNOS. Which is best in replacing Cisco L2TPv3 pseudo-wr.
