In JUNOS it can be an interface address or a router-ID (loopback address).
The latter is recommended for stability reasons. If you build an LSP to a
physical interface, and that interface goes down, so too must the LSP. Not
the case for a Lo0 terminated LSP, which can route around interface
failures.
