It needs to be an address that is attach ed to one of the interfaces.
You will then need to create a static route to that address on all of
the otehr LDP speakers.

For example:

On LSRA specif the LSRID to be 192.168.0.1
then add a static route on LSRB and LSRC to 192.168.0.1/32 via the
next hop.

A general rule for LDP, if you can't ping it before running ldp_linux,
the LSP will not get setup correctly.
