You mention this being a ring - if you target the LSP to a loopback, your IGP will provide an alternative path after a failure. Sometimes it is a feature - more than once I have come across a request for if it fails, it fails type of service meaning cheap nonresilient connection. And LSPs destined to link IPs and coupled with strict EROs fit such requirement nicely, but I digress...

[j-nsp] MPLS Endpoint Discussion
All, I've created simpler MPLS ring between a total of 6 MPLS 4550s. My questions what IP do I use for the Label Switched Path Endpoints. I can't seem to find a best practice. Specifically this code Obfuscated as I'm a little to literal with my descriptions set protocols mpls label-switched-path PE2-to-PE1 to 10.254.1.1 set protocols mpls label-switched-path PE2-to-PE3 to 10.254.1.6 set protocols mpls label-switched-path PE2-to-PE4 to 10.254.0.4 Do I use the /30 that exists between the Legs? Or should I use the LoopBack0 ? My thought would be Leg itself as it creates the path. But some documents state LoopBack.
