I'm back to studying Service Provider material... but instead of continuing where I left off, INE Vol 1 Multicast Labs, I'm reading/re-reading 'MPLS Fundamentals'.
A lab I set up for AToM comes from chapter 10 of the book.
I tried to recreate the configuration from memory and being that it's only a few lines, I thought it would be easy.
I missed the configuration "mpls ldp router-id loopback 0 force" and until I put that command in, the VC never came up. This lab was for a simple HDLC connection.
What's the significance of this command? Why does the MPLS router-id have to be set?
I'm assuming the LDP router-id has to be the same has the xconnect peer. I'm guessing if I didn't for the router-id to be the loopback but specified the outgoing interfaces as the xconnect peers, it would have worked. Time to lab it up.
*** Edit 2
Odd, I tested it out, removed the mpls ldp router-id force command, clear mpls ldp nei *, xconnect to the serial interface of the remote end, the L2 VC circuit showed up, but the CE router interfaces never came up.
