I love to be the “uncola” of networking sites. I like interop and I don’t do a lot with Cisco because I don’t have access to much of their gear anymore. So, that being the case, I had a need to bring up a l2circuit (in JunOS speak), or VLL (in Brocade speak) between an MX480 and an MLX. Since they are very different platforms, I had to do some digging and playing around to get it to work. You should have a rudimentary understanding of MPLS (which is about what I have) to do this. l2circuit / pseudowire / vll are all synonymous for the scope of this post. JunOS:
